When you add a caption to an image in Google's Picasa/Picasa2 (and other image editing programs) the caption is saved to the actual image in the header section called IPTC data.
There is a script called "Enhanced Simple PHP Gallery" that I use as a gallery for this webpage and many others mainly because its so simple to operate. Normally if you wanted to add a description to a file you would have to use the administration page or manually edit the "sp_descriptions.ini" file. This can take a lot of work and if you ever switch gallery scripts all your descriptions are lost.
What I have done is altered the gallery script to check for the title and description from the IPTC data when it is loading an image.
I have altered the Enhanced Simple PHP Gallery to include my changes. All you should have to do is upload the contents of this zip to your webserver with some images.
