Hello,
When you use PrettyPhoto popup system for galleries with more than 20 images or so and you wish to use overlay_gallery setting (responsible for these little thumbnails slider when you hover on the image), SIG PRO becomes unusable.

The reason is the way thumbnails in PrettyPhoto work. It uses full-size images and then crop them with CSS instead of taking them from pre-generated thumbnails (50x50) for example. The result is, when you wish to click on latest image in the gallery, you end up waiting for all the gallery images to load before you see image you wished to see. Sometimes, for galleries with images 20+ it means couple of MB to load before you see the image.

This problem is explained and addressed in details here : forums.no-margin-for-errors.com/discussion/1597/prettyphoto-enhancements-fixes-development/p1

There is a way to fix this, Vladimir at prettyPhoto forum found a solution and developed fixed version of js library, in fact it is going to be incorporated in official release soon. But to handle thumbnail generation, it would be perfect to code these little thumbnails generation function inside sig pro when popup parameter is set to PrettyPhoto.

Please consider this request as this is not anything sophisticated cause you already use gd lib to make thumbnails, so I think it is worth doing.

Take care
