Thanks Jake!
It's not a permanent solution, though, it is just a temporary image replacement done through a java script that only you can see! So you are not changing the actual page, just what you see. So you're not in danger of changing images to the site that the public sees. Still, I wouldn't want to see her pictures associated with bad sites anyway, even if it were just me.
With that said, every time you visit or refresh a site you will need to click on that bookmark that was set up to see Alizée's photos replace all the ads! And you can click on the bookmark to see different sets of photos each time!
If you go to ebay and do it, it looks like Alizée is for sale! lol!... except for the descriptions of the links... you can tell I have been browsing cat condo's lol!...
