From the developer:
CCCP hides and unhides an UTF-8 Text in an image. This version has support for 2 hide methods with various options and supports TIFF, PNG, GIF, BMP fully and many others (e.g. PICT) only half.
You may want to check out more software for Mac, such as Umajin, MultiTouchFlickrViewer or Photoshop 101, which might be similar to CCCP.
