A) The free panels for VRA might meet your requirements. There is a
portion for the (art)work pictured, a portion for the image, and a
portion referencing the collection.
This is an "essential" subset of the VRA Core 4.0 (XML) metadata
schema used by museums to catalog images of artwork.
B) If you have existing CS3 File Info Panels that already meet your
needs, then you might be able to convert them to CS4/5 File Info. A
java script and procedure were provided on this forum in July 2010.
