Automated Thickbox/Fancybox Gallery

I’m new to wordpress and was trying to find a plugin that will automatically create a thickbox-type gallery when my client uploads pictures. I found “Auto Thickbox” but that is not compatible w/ v2.8. Anyone have any suggestions? Otherwise, is it difficult to downgrade my wordpress version so that its compatible w/ the auto thickbox plugin. I really appreciate any help or advice!

Thanks in advance,
Brian
