My concern was more about privacy. I don't mind if users see and copy artwork, seems like the spirit of Web 2.0. But I was wondering if sites can monitor you in that regard.
From my understanding of the Print Screen button, the copy of w/e image you chose is saved locally on your computer, but I was wondering if public sites monitor key entries (such as the Print Screen button) or if ur own computer broadcasts to a given site that its performing a Print Screen function. I always thought that if a site did monitor ur print screen activity, or any other key for that matter - what would stop those types of sites from monitoring what you're typing if the next tab on your IE or FF browser is your bank account & such..
