Celeb sites will get their turn. The stars will finally have enough of it, have some spare time and do a National Enquirer on those sites. And the NE was proclaimed to have a marginal 'fair use' since they *are* a publication. The laws that were made for net copyright really nail down what is and is not fair use. So if your site isn't
www.cnn.com then don't plan that as a defense.
No one else rememeber the falconfoto win awhile back? They drilled a copyright thief dead to rights.
But under no context can what the webmaster is using the pics FOR come under the actual ruling in the cases UNTIL it comes down to the monetary award. Then the tab goes up if there are banners to make $$ there, go up more if its under a member area etc. This infringement thing doesn't allow for changes to be made to 'make it yours' on an existing pic either. As long as some one elses model, background, etc are present in ANY form... Bang.
So if you don't have a legal release-license in your hot little hand then better not be using something. Sites doing this can also open up their host companies as well as others to the same charges.
