I'm a member of a non-profit which has a collection of photos (3000 currently but will be growing) which have previously been sold in the form of a book, but we want to move to an annual subscription service for fee which would give subscribers access to the photos and related information. Would want to be able to categorize and label each photo, but also have searchable tags for each item including manufacturer, subject, descriptive words, etc. If the subscriber could build their own gallery of photos it would be great. I'm looking for a web software that has such feature, and am hoping someone will know of one. Otherwise we may have to find someone to develop custom from what I've read here.
