You should be more honest and re-order 1 and 2. Putting affiliate links into Google search results isn't even in the same category as taking a screenshot of a page. Why "scratch that itch" in an extension that is completely unrelated unless your primary interest was to make money.

Now there's nothing wrong with making money, and I don't even disagree with the way that you attempted to monetize the awesome screenshot extension (via affiliate links). But be honest with users about your motivation. Most will understand.
