I would like to back up the leeriness.  While not a graphics guru, 
this will make the color mapping strange and the jpeg compression 
algorithm (lossy) discards data from the image.  However, perhaps the 
I doth protest too much because it IS a thumbnail.

I use photoshop to add a watermark and make thumbnails.  We are just
taking baby steps into this area, but if you want to see some of the
images, try

for the Fort Worth Star-Telegram Photograph Collection.  This is an 
exhibit which we hope to be able to transform into a full fledged 
imaging project and search service (funding permitting 8-).
