Claims to be a free image viewer. Which it isn't. OK, it's free (but not, at least when I last looked, open source), and if it can't open an image you'll probably struggle to find anything similar that can. It's actually also a very intuitive and capable image editor.
I believe it can be installed under Wine, but I've not tried myself
