I usually click the little camera icon which lets me enter the URL of the JPG file I'm searching.  E.g., www.indygirlshomepage.com/gallery/image01.jpg  or, more likely, backpage  

The results are based on an IMAGE search, not a text or URL search or a mind-reading algorithm.  I might find zero hits other than the original pic itself.  That's an indication (but NOT proof) that the pics are hers alone and not stolen from some other web site.

There might be hits for her other authentic ads and websites, also a good thing, that the search is working.  

Hits for the same pic being used by too many different names and numbers in too many cities and countries means she's probably a fake.  Google might even find out that the pic belongs to a reputable or famous non-XXX model and the provider has probably stolen the pics.

Google images won't find direct links to TER because there are no images (other than a few on the main page) stored on TER to be found.  

Click on the hits and see if the web sites they are on have links to TER
