imgcat[1] is one of my favorite terminal innovations as of late. I thought I'd take a long shot and see if it worked since that functionality seems like it would be simple for a browser-engine-based terminal to handle, but sadly no-go. I smell pull request.

Just 'cat someimage.jpeg' or 'cat someimage.png' and it'll display it right there in the terminal. Works great if I do say so myself (I wrote it =).
