I had previously created a script-fu to automatically emulate the results of shooting on expired Polaroid 600 instant film that included the undeveloped corners that results from old film stock with not enough developer/fix to completely cover the image area:
These are plugins re-compiled for Gimp-2.7.5 (latest LAST pre release before Gimp-2.8)

Install directions are also available at the above link.
Takes a heavily-packed sprite sheet with no padding between sprites/tiles and adds padding or spacing. Can also create a "gutter" around seamless tiles, filling the padding with the tile's edge pixels, preventing seams from appearing when using the tile in a 3D rendering environment due to interpolation.
Can also remove padding/spacing from a sprite sheet.
Update Version 1.1 (5/17/12):
- Script now supports non-opaque sprites
- Moved scripts to Filters > Sprite Sheets menu
Steganography tool to hide/retrieve text or an image in an image.
Once data is hidden in an image, one can't tell the morphed image from a bunch of others (even similar looking).
Open any image and run Filters>Steganography>Hide to specify an input text file or image[lossless]. This will hide the data within the opened image. You can then save the image as a png/bmp/lossless format.
