Watermarking either works well, or not at all. In either case, the watermark is added when the image is first uploaded. Thus, disabling/enabling watermarking will not modify images already in the db.
Known Issues
The "Manage > Profiles" menu appears to have some issues under internet explorer. Theses are under investigation. The display section works flawlessly under IE. In the meantime, use !IE for administration.
Please post any questions or bugs to Christopher O'Connell. Feature requests and comments of a more general nature are welcome, however, they will likely not be implemented immediately.
