Fffforgot is a Greasemonkey script which removes all images from popular image-sharing site FFFFound (and now-defunct ImgSpark) and can be edited to work on any other site of your choosing. This script is a response to the growing proliferation of image-sharing sites which drastically increase the speed by which images are rendered inert and disposable: decontextualized, consumed, and then forgotten.
Use of this script requires Firefox, Chrome or Safari with the Greasemonkey (GreaseKit) add-on enabled.
