thumbnails only loading when scrolled to bottom page

Hi,

Please try out the following:

Create a page with only a gallery, with plenty of images. I noticed the thumbs sequential loading only starts when the users scrolled to the end of the page/gallery.

This is also if you choose a big preview image. As soon as the gallery requires to scroll to see the bottom thumbs, it only displays the thumbs (starts the sequential animation) when reached the bottom of the page/gallery.

Before doing this they remain semi-transparent.

How to solve this please?

Thanks

S
