If the photos are TGTBT and there are no reviews... Put the put url into tineye.com. It will search for the image on the web. If nothing pops up, thats one more piece to confuse you. You will then have to use common sense and you're magic 8 ball to decide.

Often, the image will turn out to be some playmate or FTV gal...

When installed you simply click it while on the page and it brings up all the photo's from the page and you click to see if they are in their database.

There is also a plugin for "any browser" at http://www.tineye.com/plugin

I use the Google Chrome browser with the incognito window, which keeps no web browsing traces.

Follow the instructions to drag the link to the browser bookmark bar, then drag the image to the bookmark. It works just like the TER search plugin.
