Hi there,

Is it possible for the background images to be selected randomly ?

many thanks.

Hi, yes. Use this option

 startRandom: false,             // start on random slide  

Hi,

I’m not able to use the script.

I always have this message : “TypeError: $(...).backslider is not a function, centerImages: true”

I can see the images, but they are loading really fast, and finally, I only see the last one… I read the images from a directory.

Here’s my code :

In the HEAD

<link href="css/backslider.css" type="text/css" rel="stylesheet"> <script src="js/jquery-1.10.2.min.js" type="text/javascript"> <script src="js/jquery.easing.1.3.js" type="text/javascript"> <script src="js/jquery.backslider.min.js" type="text/javascript"> <script type="text/javascript"> $(document).ready(function(){ $('#bs0').backslider({ mode: 'pagination', effect: 'slidefade', effectEasing: 'easeOutCubic', effectTime: 2000, centerImages: true }); }); </script>

In the BODY

<div id="bs0" class="backslider"> <ul class="bs-slides"> <li> <img title="Image 1" alt="Pic" src="upload/diaporama/image1.jpg" /> </li> <li> <img title="Image 2" alt="Pic" src="upload/diaporama/image2.jpg" /> </li> <li> <img title="Image 3" alt="Pic" src="upload/diaporama/image3.jpg" /> </li> <li> <img title="Image 4" alt="Pic" src="upload/diaporama/image4.jpg" /> </li> <li> <img title="Image 5" alt="Pic" src="upload/diaporama/image5.jpg" /> </li> </ul> </div>

Could you help me please?

First of all every <script type="text/javascript"> must have closing tag also. <link> tag however does not have closing tag.

yes, this is already corrected. The slider is now working. But the links of my menu still not working (not only the menu, but all the links in that page), all my links have <a href=""></a> code

Make sure you have correct z-index for your links. Maybe some other element is covering them and that’s why they are not clickable.

Hi, I have a pre-purchase question.

Is it possible to remove the texture over the image?

Thanks in advance

Hi! Yes, I can explain how to modify existing slide templates.

Hi, a presales question. It would be nice if there was an effect of zoom in and slight rotation (image viewing, not transition). Also, this script can be applied to part of background or it has to be full screen?. thanks.

Hi! Thanks for suggestion. Yes. it can be applied to only part of document or it can be even used as standalone slider. See FAQ here – http://codecanyon.net/item/backslider-fullscreen-background-image-slider/2756199/faqs/18473

This one looks promising! I’m comparing a couple of fullscreen sliders here. Yours also has an issue with Android 4.1 and newer: The images show up distorted/stretched on devices running this system. Any plans on addressing this issue soon? Thanks.

Well. I have tested backslider with browserstack and I haven’t seen that images are distorted. My preview has “centerImage” feature, so maybe this confuses you. Also I use both landscape and portrait images in my demo, which fit differently into the mobile (portrait) screens.

I’m certainly not confused about this. Maybe your “centerImage” feature is the reason, I don’t know. But the images are definitely distorted on Android 4.1+. No matter if portrait or landscape. Probably because I’m feeling slightly insulted I just spent 15min to show you the results with screen shots here: http://www.pingdesign.net/fullscreenslider/

Thanks! I have tested again and was able to see the problem with Android 4.1. That happens if device orientation and image orientation are different. Also I found explanation to this issue https://github.com/srobbin/jquery-backstretch/issues/188#issuecomment-14068446 . I will try to find workaround, but I suppose this is a bug in Chrome on android 4.1

Testing my site locally the backslider plugin works great! I just tested the site live and it is not working at all. Could you help me?

Problem is following – “Failed to load resource: the server responded with a status of 404 (Not Found)” for css/backslider.css

Thanks, I realized I was referencing css and the folder was actually titled CSS. Great plugin! It really is the nicest full screen gallery I have found!

Thanks! :)

howdy, whats the best way of putting backslider in the background :)?

http://promisedlandretreat.com.au/index-start-over-fancyfull-bs.html#gclower

I tried changing .backslider z-index to -1, but the slide flickered on transition – became very glitchy. I’ve narrowed it down to the .backslider .bs-controls. When these zindex> .backslider zindex then it flickers.

I’ve been at this for days (with a different backslider, which I ditched in facour of yours:)), any help would be appreciated

That may happen if you backslider somehow interferes with CSS3 transitions or may have any of CSS3 properties applied. In what browser you have this problem?

chrome on windows

I checked your site in chrome browser (win7) but I don’t see any glitches. It works relatively smooth

Hi.

Is Flickr photo range limited to 20 photos? I need show so many more.

Thanks.

Hi! You will be limited to 20 photos if you use free Flickr feed. To show more photos please use Flickr Auth mode (“flickrAuthQuery” plugin option)

I have tried to use ‘flickrauth’ but it doesn’t work. I’m typing correctly the api_key and the photoshet_id, but i don’t see any photo.

You should use these options in plugin configuration

 photoSource: 'flickrauth',  
 photoRange: '', 
 flickrAuthQuery: {                
         api_key: '000000000000000000000000',  
         photoset_id: '1111111111111'  
 }  

If this won’t work please contact me using mail form on my profile page and give me a link to check your problem. Thanks!

Hey there, I have implemented the code as suggested but it doesn’t load properly. What did I do wrong here?

http://www.kernbohrer.de/produkte/kernbohrer-vergleich.html

Thanks

Hello! I don’t see your site loads backslider JS file or there is any init code for plugin.

This is a good little plugin, and does what it says. However the docs could be a improved a little bit. The author has outlined the options, but not explained what some of them actually do, or what each value of an option does. At the moment I have to dig into the code to se what some options actually do.

Thanks for comment! Every option has short comment beside it explaining what it does. And you can always ask me to explain particular option if it’s not clear

Hello,

most likely I have just oversaw it but how can I adjust the duration for each image before changing?

Thanks,

Hello! Option that you need is called “effectTime”. Check plugin documentation, section “4. Configuation”. Thanks!

Hello, not how long the transition takes. I mean the actual time an image is shown. So if it’s currently shown for 3 seconds, how can I adjust it to be visible for 5 seconds?

If you use “timer” mode, delay you can adjust with

timerDelay: 5000,               // slideshow timer delay (for "timer" mode) 
option

FlGravity,

Great plugin! I’m thinking of purchasing and have one question up front. I do not want the background images loading in from flickr or another photo site, is it possible to have those load from images on my side (image folder/server)?

Thanks! Yes, its possible. You need to set photoSource option to ‘none’ and provide images directly in markup as UL list.

Hi, just bought the backslider-plugin, but where to change mode? i need the scroll down- bg-change mode – like demo -, what code to change/put where to get it?

thx

Hi!

Mode you can change by setting “mode” parameter in plugin init

mode: 'controls',    // mode - "controls", "timer", "scroll", "pagination", "thumbnails"  

Please refer to plugin documentation for more details. And if you have any other questions I will be happy to help!

Hi there,

two questions: 1) Is it possible to have a bg image? I tried but it didn’t seem to work and I would like to have the first slide instead of the black background before the slider starts preloading.

2) Is it possible to have an auto slider as well as the ability to change the images manually=?

Thanks,

Hi! 1) If you don’t want image preload you can set “preload” option to false. 2) Yes, it’s possible but you will have to implement this manually. In comments you can find few examples how to do this.

hi there

can we have please: thumbnails+autoplay? thank you

You can do this like so

$(document).ready(function () {
    $('#bs0').backslider({
        mode: 'timer',
        effect: 'slidefade',
        centerImages: true,
        slidesLoaded: function () {
            var bs = $(this);
            var size = 50; // thumb size
            bs.find('.bs-slides img').each(function (p) {
                var atts = this.width > this.height ? 'height="' + size + '"' : 'width="' + size + '"';
                var thumb = '<img ' + atts + ' src="' + this.src + '" alt>';
                $('<a class="bs-thumbnails" href="#">' + thumb + '</a>').
                css({
                    width: size,
                    height: size
                }).click(function () {
                    bs.trigger('backslider', ['skip', p]);
                    return false;
                }).appendTo(bs.find('.bs-controls'));
            });
        }
    });
});

thank you for your help! this is working great!

Hi flGravity, Are you able to give more information on how to get your script working with both a timer and thumbnails. Any help would be much appreciated.

I received your email and will reply in a minute.

hi there, is there a hack to use ‘timer’ along with ‘thumbnails’?

The primary plugin mode should be set to timer. And the thumbnails you will have to generate with external JS code and link using plugin API skip method

$('#bs0').trigger('backslider',['skip',N]);  
, where N is thumb index

Hi. We’ve implemented BackSlider on this page http://www.africanexplorations.com/ however is there a way to reset the delay of the slide if you use the pagination? You’ll notice is you try navigating through some slides change very quickly because of the timer.

ok. The problem is that “reset” does not work if backslider mode is not timer. You need to set mode to timer

I want both the timer and pagination. The ideal is to have the banners scrolling on a timed transition, as well as giving the user the ability to take control of the banners if they wish. This is quite common with a lot of sliders.

Yes, I understand that. But the problem is that my plugin can work only in one mode at a time. I recommend you instead of modifying js file set “timer” mode and then add next/prev buttons manually to the backslider div

<div class="bs-controls" style="display: block;"><a class="bs-previous" href="#bs"></a><a class="bs-next" href="#bs"></a></div>

then link controls with corresponding api methods, like so

<script type="text/javascript">
var bs = $('#bs0').data('backslider');

$('.bs-next').click(function(){
 bs.next(); return false;
});

$('.bs-previous').click(function(){
 bs.previous(); return false;
});
</script>

Hi,

I am using WP theme Teddy, which is using your plugin for background images. I am having problems with centering the images during window resize. On the phones it is always alligned to the left: http://www.skyform.eu/blog/

I read your update about ‘centerImages’, but it isn’t working in Teddy.. Can you help me what to do, please?

Barbora

Thanks for contacting me! Author of Teddy WP theme uses old JS file for backslider plugin that does not have image centering feature. Please ask him to contact me and I will give him latest files of my plugins. Then he will provide you with updated files of the theme

Thanks! I asked him to contact you and he sent me the file right away. Amazing :)

OK. Great that you have solved this!

Hi
Please, no recourse to AUTOPLAY??? Thanks

sorry! mode = timer :)

Yes, exactly!
