Or, if the watermarks *must* be dynamically generated and visible, use something like ImageMagik to lay something transparent over the image on the fly. Wouldn't be exactly speedy, but would do the job. (I've seen this done on a few sites before -- visible graphic watermark is customized for the logged-in user.)
You may be able to pull this off with the GD 2.01 tools also ... I haven't messed around too much with the alpha transparency capabilities the 2.01 library allows.
