Selecting Large Amount of Small Specks

[Ofnuts]

A small script. Adds a Gimpy222 menu to your image menubar. Several entries, for 1 to 5 pixels of grow-shrink.

I suggest you try a few values on the a first couple of images, then either you use Ctrl-F to replay the same filter all along, or you set a keyboard shortcut for the one you use often (seach for "gimpy222").

Have a look at my  ofn-file-next script to go from one image to the next if mass-editing.
