My girlfriend has photos of her ex in her purse?

I was asked by my girlfriend to get a card from her purse. She never uses her purse normally just carries them around separately in her pocket, unless she needs a certain card that she hardly uses.

As I put the cards away I saw a photo of her with her girl mates, then I noticed her ex boyfriend next to her with his hands on her hip. I didn't mention it at the time, I had a quick look to see if there was anything else and found another photo of her, her girl friend + her boyfriend and her ex in a photo booth pulling faces.

Should I be worried or annoyed?

It isn't like she uses the purse alot, I hardly ever see her get it out. I just kind of thought she would have taken them out by now we have been together a year and a bit
