Is there a way to use google to find something in the page source of a page? For instance i could type in the url of an image or song to find a page with that picture or song in it.

It would be neat to have this. All we got is Google code search though.

Google also once analyzed the source of webpages:

I have some pictures hosted on some random old blog of mine and i'd like to know where they're being used. Any tips?
