If the photo is on a text message, it would be evident. Since you're asking this question, I assume it's stored on the phone instead. If that's the case, then there might not be much you can do aside from asking your husband directly.

The real question is: What were you doing going through your husband's phone in the first place?

Wait... Rather than confront your husband directly you want to call this person and harass them instead? Any questions you have about their relationship can be answered by TWO persons and you ALREADY know one of them. Don't play private investigator. Be a grown up and ask your man.

I'm dying of curiosity. Was she naked? Was the body tight? Of course, you DO realize that one of his friends probably sent him a picture of a stripper. My friends used to do that ALL the time...until I got new friends.
