I agree with what others have said here regarding real, recent and candid pictures, or as I like to call it "proof of life", a concept which takes it a step further. What pulls me in is seeing real, recent and candid pictures, particularly if they are taken in public places that can be identified as an actual location in the DFW area (that is NOT at/near your incall, which would be be attracting the wrong kind of attention to your incall area).
Example: A candid picture of you at a well known local bar or restaurant, sports venue or city landmark. This tells me that you are [A] a real, actual 'regular' person and not a picture of a pornstar, model or amatuer flasher that will be found on TinEye and [b] that you are actually and currently in the DFW area and not a picture (taken off the web) of someone else who may be a real gal, but who is actually located in any area but DFW. This "proof of life" assumes you are already posting other face pictures and is especially useful if you are new to town or to the hobby scene.
But as Dennis Miller used to say, "Of course, that's just my opinion. I could be wrong."
