With BatchPhoto Lite you can resize and rename image files and perform a few edits; the program works with .jpg, .png, .bmp, .gif, and .pcx. This program is fairly limited in scope, but costs only $20.
More advanced versions–BatchPhoto Home and Pro–add more functionality, letting you crop and rotate photos, do more advanced editing such as fixing color balance, and work with a larger range of file formats. The Home version is $30; Pro is $50.
This free preview version of BatchPhoto Lite is useful for resizing and renaming photos, but the preview function is not available–so its editing features aren’t terribly helpful.
