Anyone else with some other ideas? I keep thinking it has something to do with the watermark files themselves, but...I don't know what else to try. They're png files and I made them the same size as the watermarks delivered with core ZC.
Have you tried putting the core watermarks back and seeing if they work?, could be an issue with your watermark png? but as its working on the rollover seems unlikely

Are they are named correctly?

The only things i can suggest are triple checking the product page code, did you upload the included image handler product page or did you merge the code together with the existing page, and you haven't updated or installed any new mods since installing image handler?

note the page isn't called product page, the name of it escapes me right now, i'm sure someone much brighter will chime in with the name of it, I think its in your template or custom template folder.
