find the source of a photo

just so everyone knows…I’m going through his recycle bin because he has a problem with porn and he keeps lying to me. Yea yea, just break up with him I know. we have been together for 7 years and I don’t just want to end it like that. he hasn’t always been this way. I know guys look at porn, whatever. I don’t care about the dvds or magazines, seriously. I asked him not to use the comp (its new) for that because I use it for school and don’t want any viruses. He knows I go through the recycle bin. He’s the one who told me his has a problem with it. I don’t read his e-mail or know any of his passwords. Honestly, the fact that he saved a personal image of some chick is what bothers me. Since it’s not of pornographic nature it suggests to me there might be something more than just liking to look at it. I wanted to see if I could find where it came from because…well…what if he’s cheating on me? I’m all for working things out…but when he’s not honest with me, I dig, and at least I’m honest with him about that. And all I asked was how to find the source of a pic, not a judgement of my relationship. It used to be great, but for the last 9 months…not so great. So should I leave him? Maybe. When you love someone, it’s not that simple. And 7 years is way long enough to decide if you love someone or not.
