Lazy loading loads all images at once

Hi there!

I assumed that lazy loading would only load a few images and transfer the remaining ones as soon as the user navigates through the slider. Happens on my side with a 200 images gallery though, is that Firefox starts 200 GET requests for all images and hangs a few seconds while downloading everything. Am I doing something wrong? What I am doing is generating a string that looks like this:

'<a class="rsImg" href="' + path + '" data-rsTmb="' + thumbnail + '">' + caption + '</a>'

where path is the large image path, thumbnail is the thumbnail path and caption is the text to be displayed. This string is passed to slides when initializing the slider.

    If you use this markup, there souldn't be any problems, can you send me link to page?

    Just noticed that it's not picking up the thumbnails for generating the thumbs, but the actual images, so it seems that I cannot use the data-rsTmb attribute in the a tag. If I use img-Elements for the thumbs, I guess that would make RS load the right images, but it would still load all thumbs at once.

    Edit: Meh, my fault regarding the thumbs, I forgot to adapt the path in the JS so currently, thumbs and full images are the same. Sorry!

    This leads me to a feature-request though... Is it possible to have some sort of lazy-loading for the thumbs that loads only the visible images x 2 for example and fetches the other thumbnails only when scrolling the thumbs-strip?

    Unfortunately, thumbnails are not lazy-loaded (mainly because of performance, no-js and SEO reasons), and currently there are no plans about implement this feature.

    200 images per slider with thumbnails is way too much, try to separate galleries by categories and optimize images.

    Sprites for what? For thumbnails?

    Right. :) I guess loading one larger image is better than many small ones.

    It is, but see my prev message - SEO, no-js.

    I agree, but when adding slides via JS (the slides property), no-js and SEO doesn't matter anyways. :)
