R-rated censor+Image rating sorting?

[Jamie Lee]

Hi. Is there a way I can make a thumbnail show an R-rated warning without having to manually edit an image's thumbnail? I don't want a bunch of different files in my server all showing the same thing.

Edit/ Also, is there a way I could make is so I could appropriately rate what a picture should be (G/PG/etc.), and allow browsers to show only images from that rating catagory if they so wish?

Probably the easiest way would be to sort them by album, i.e. all 'R' rated pics in oe album, with the warning in the album description.
