highslide_thumb.png If you are using Picasa extension I published while back you might want to take a look at another choice and try to use HighSlide JavaScript library instead of the LightBox. Just take a look at this post by Radim Boušek and get it there along with instructions. I’ve never herd about HighSlide before, but it seems like a nice thumbnail viewer with Ajax support and more options, so give it a try.
