While graphic design professionals probably wouldn’t be able to substitute 
Fotografix for Photoshop, it’s certainly a capable free alternative for the average Joe.
In addition to being totally portable, Fotografix has a ridiculously small footprint. It’s a 370Kb download and about 700Kb once extracted. Despite its size, most of the features I rely on in Photoshop are available. Fotografix supports layers, masks, and scripting, comes with a few key blur and stylization filters, and type layers are editable (unlike some other editors where text is a one-shot deal).
The usual editing tools are also provided, like rectangular and elliptical marquees, magic wand, rubber stamp, eyedropper, and gradient tool. For me, the only glaring omission was the lack of grid and ruler options. Regardless, I didn’t have any trouble accomplishing my daily blog-editing tasks with Fotografix.
No, Fotografix isn’t a replacement for Photoshop, but its good range of features, small size, and portability make it an excellent option for quick edits on the go. The price is hard to argue with, too.
