I have a website with some large images. They are resized by default, but when you click on them, they open in a lightbox and become larger. I’d like to let the search engines know the original (bigger) images, instead of the smaller resize images included in the source code. Is there a way to let them index the bigger images?

You can’t decide what google chose to index (but you can make it easier for google using thepiyush13 answer), but you can tell it what NOT to index.
