Google Image Search API

I really really needed an API to query images from Google programatically. Since Google don't provide such an API and I couldn't find anything worthwile on the internet, I had to do it on my own.
If you're interested, I posted an article on The Code Project:

Please, if you liked it, place a vote - I'd like to know what people think of it.
