iWatermark, Script Software’s watermarking utility, has been updated fixing many bugs in the application.
Among the fixes in iWatermark 3.0.11 are the ability to auto save watermark changes, a workaround for incorrect metadata on the Nikon DX2 when using Photoshop and a fix when converting dates, among others.
You can use iWatermark on entire folders or individual images. You can also create thumbnails, rotate and scale and set the transparency of the watermark.
iWatermark integrates with Photoshop, ACDSee, iPhoto, Cumulus, Portfolio, PhotoStation, iView and other photo organizers. The application requires Mac OS X 10.3 or later and costs $20.
