Images Don't Help You Rank on Google

Although the images that you use on your web pages can tell a story as much as the words do, they don't help with your Google rankings.

This has been confirmed by Google's John Mu:

I understand that nobody likes looking at blog posts and feeling like they’re reading an essay.

I also appreciate that a picture paints a thousand words.

Images can also help social sharing and cut through any language barriers, so I appreciate their importance.

However, you don't need them to rank on Google.
