Eltima Software (http://mac.eltima.com) has updated PhotoBulk, a bulk image editor for Mac OS X (10.7 and higher), to version 1.5. The new version allows for faster changing of the watermark position int he preview window and the ability to choose the most precise position for your watermark per-pixel.

PhotoBulk lets you add text/image watermark, resize, and optimize hundreds and thousands of images or photos in just one click. You can check how your files will look like before they're processed. PhotoBulk remembers the settings you used last time, so you won't have to set all the same options again to redo customizations for another pack of images.

What's more, you can optimize file size of your JPEG or PNG images while keeping their original resolution, quality, and format. (Note that PNG optimization is time-consuming and works slower than JPEG compression.). Supported formats include JPEG, PNG, GIF, BMP, and TIFF

PhotoBulk is available on the Mac App Store (http://tinyurl.com/br6mrx2) . The cost is US$9.99. A demo is available at the Eltima web site.
