How to capture image info when it's mouse over

The "correct" way is to link to the page the image is on. That way, you are not "stealing" the image for your own use, you are just telling folks where they can go look at it.

(that's my photography enthusiast copyright infringement is stealing response).

Sometimes, if you left click on the image, it will bring up the actual image in a new window and then you can right click to get the image link.
