i.Mage

i_mage.png i.Mage is a small footprint graphics editor for Windows. It’s open source and is there for only simple editing of graphics. The support of graphic formats is minimal but is enough for the couple of more useful formats. It can do grayscale, inversions, alpha blending and most of your more general purpose editing functions.
A great little open source project that loads fast and edits fast, and compiles fast.
