I mean jpeg images, like the one I sent you "Virgin of Guadalupe". I saved from a website, after clicking an enlargement. Why not start by posting this one - at least we have the Virgin's blessing to the project!It saves at about 165k, I have others, they seem to average 100 to 150k, are fairly low resolution. So I think a ceiling of 200k per image is more than adequate - you would have to have absolute discretion on what goes up, maybe even a delay so that you can confirm copyrights, or if you attract the juvenile crowd posting porn as a joke.

In this age of Napster/mp3's, I think the copyright issue is wide open. For example, www.antiquitiescollection.com, has 100's of fresco subjects, all can be downloaded as jpeg. They certainly don't own the copyrights, and I doubt that the fact they scanned them or merely posted them on their website, gives them any special rights. Besides, we are interpreting scans as references and education - they are printing them untouched to make a quick buck.

You know the mechanics of your site. I have no idea how much space this would take. I do have a good idea as to what people expect to see when they hear the word "fresco" - and they are not seeing on this website now.
