i really have to apologize for the hosting. i'm using some experimental hosting software instead of a battle hardened solution. if anyone is having issues with the site you can clone your own repo and just open the index.html in your browser locally without installing anything.
site will become more stable over then next few weeks.
You are very right in your comment. I have ascii coding laying around right now in JavaScript that can take any image and convert it into ascii, but making it work server-side is going to be hard.
If you think you can help with any of this drop me a message on the github.

However, automatically generated ASCII images aren't really art, either. It's just the generators themselves which can be called art. ASCII art almost always requires some tough hand work to become really good. For example, have a look at the Star Wars Asciimation (http://news.ycombinator.com/item?id=1446358).
also, it should be noted that online demo creates a contact card that uses every single API call. normally you wouldn't generate a UK address + a US zipcode in one contact
