We've been testing against IE8 on Win7, which we've managed to get working.
We've gotten a few exceptions earlier (which we assume were from you :-D) We'll take a look at the logs and try to figure out what went wrong, sorry about that.
Oh, I see what you are getting at. You are right - an image is unnecessary currently, but we have features implemented that do image analysis that will be available in our next release.
We are doing the processing server side, so that might be slightly difficult, but we are intending to make the process automatic, including auto-finding the divs.
here's an example of our auto-detection algorithms:
Overall, the idea is to automatically turn a mockup of a page into HTML. This is predicated on the user having a picture of the page they want, whether it be a photoshop drawn file or by hand.
In this version, we are outputting floating CSS (with padding, margins, etc) & intelligently named divs, which is intended to save web devs time on getting all that together by hand.
