Where is my desktop image saved?

[Flying Sq]

I'm currently trying to transition from XP to 7, and I want to keep the same image, but I saved it from a website, (right click: use as background), and can't find where it was stored. This would be a problem, but the site went down, and i've tried to find it for hours.

open the screen where you can change the wallpaper and get the name of the particular image and do a search.
Then copy it to where ever you would like.
