ruby-fastimage - 2.2.1-1 main

FastImage does this minimal fetch for image types GIF, JPEG, PNG, TIFF,
BMP and PSD.
.
And it doesn't rely on installing external libraries such as RMagick
(which relies on ImageMagick or GraphicsMagick) or ImageScience (which
relies on FreeImage).
.
You only need supply the uri, and FastImage will do the rest.
