Fimg is a Windows 32 bit (Should be compatible with Windows 95 onward) image editor designed for editing game sprites and images. It currently works with Quake SPR Sprite, WAD2 and Lmp along with a smattering standard image formats. The base image format support is provided by DevIL.

I developed Fimg for editing the new (and as of yet unfinalized) Qake sprite format that will appear in the next version of Qake. However, my secondary goal was to make a tool to basically replace AdQuedit's functionality, as AdQuedit has several issues (such as being known for deleting people's mods and not working with sprites containing framegroups).

I also have the secondary goal of making it a general image viewer, encompassing all the features of my favorite viewer WebImage, but that goal is still a long way off. The current state of the program completely mimics all relevant AdQuedit functionality. The features I considered irrelevant are of course PAK file extracting, model scaling / skin editing (which I may one day add, but I suspect people would just rather use qME for this task) Although Fimg has features that support Mip textures in wad2, Fimg is really best suited for editing gfx.wad only, much the same as Adquedit). Fimg correctly zero-fills wad entry names, unlike Adquedit, so wads edited in it will not be messed up with GLQuake (See QIP).

It's also useful, if you're using a primitive image editor that does not support editing of alpha channels in 32 bit targas (such as those used in DarkPlaces and other engine mods), for editing the alpha channel of such images. When doing this, I recommend using the Copy and Paste Alpha Channel commands from the Edit menu to import and export directly from your image editor.
