Tag pictures with graphics

Dear owl-guy,

I’m doing a site for a second-hand furniture dealer (vican.se/wordpress) who’s decided to do a bit of new furniture as well. Now they want to tag the used furniture with a diagonal ribbon in the upper right corner of each portfolio-item saying “second-hand” to indicate that the item is used. So far so good.

The graphics itself is not the problem, but the idea was that in the end, the editor (not me) could easily tic a box in edit mode on the specific item saying “second-hand: Yes/No”. They’re not too keen on photoshopping in each ribbon on every second-hand item.

I’m open for feedback or other solutions on how you or anyone else in the community would tackle the problem. Big thanks in advance. Great theme by the way.
