Long, long ago when I began in this crazy world of fun I used pictures that were a representation of myself. I did this for my safety as we all have real live careers outside of the play area:) I was called out by clientele and from there on fixed the situation. Now the photos I use are of myself, with only a sliver of my face showing. In the end it's up to you what you decide to do. Personally, looking back, I should have just used my own photos.
Cheers!
