Do you think he is wrong or am I overreacting?

I sent him a picture before we met in real life. At the time he said he liked it. Recently though, after we met and are getting on really well, he has confessed he doesn't like that pic and deleted it. It made me sad and more so because he saved some other girls pics (before we met) but hasn't deleted them when he recently cleaned his picture folder. What do you think?
