I found this web site last year where you can post and map out your photos of Yosemite (or anywhere) which later posts the vista photos on google earth. It used to be a european (spanish, I think) website, and at some point google bought them out.

It's is a pretty good resource for checking out places you have yet to go to get a feel for what they are like.
