Adapting Gallery to display Artists Paintings & Artworks

I am desperately looking for a program that can do this... perhaps Gallery can be adapted.. perhaps someone out there has done it.. maybe Bharat is looking at developing one.

Here is what I need. I would be glad to beta-test.
I need to set up one for an Art Gallery.

1. Exhibiton to replace Albums with the ability to add text description for each gallery

2. Database to be defined under 5 main categories:-
- Painting
- Drawing
- Mixed Media
- Sculpture
- Multimedia
3. Each art piece, which should fall under 1 or more of the categories above to have the
following labels/fields
- Artist Name*
- Artist Biodata*
- Date of Birth
- Education*
- Artist Details(multiple txt line)*
- Title of Artwork*
- Year Produced
- Medium(oil, water color, charcoal, mixed media, etc)
- Dimension of Artpiece
- Acquisition #
- Image #
- Exhibition History*

4. Customisable Caption displayed on all thumbnails(size admin selectable)

5. Customisable Details Labels/Fields on full size images(size admin selectable)

6. Option for comments to be placed by visitors and send as email for full sized images

Notes:
1. System should allow thumbnail browsing or searcheable for the fields marked *
Search field to be displayed on all pages

2. Thumbnails to be automatically generated, dimensions to be selectable by admin

3. Template based to allow for customisation and adaptation to overall site design

4. Have option for authorised client staff to upload and post captions/details

5. Php and MySql based

6. As one Artist details may span across several Artworks, Artist's Details can be
served up as a pop-up page(more importantly, it should not be required to enter
artists details for different artworks produced by him/her)

I like the layout that <!-- BBCode Start --><A HREF="http://photography-on-the.net/gallery/" TARGET="_blank">Exhibit Engine Online</A><!-- BBCode End --> has produced, but unfortunately, the author was not too responsive to my request for modification.
