I've only read through the first ~15 replies and lat couple, so apologies to those guys lost in the middle who may have contributed something worth while, but......
I'm genuinely surprised at the amount of people saying "just leave it" or "just hope you meet a girlfriend that isn't clingy/needy etc". I'm not the jealous type at all, and my last girlfriend who massively so. To the point where she wanted any photo with me half naked (or fully naked as some were

) or that had anything to do with an ex removed from FaceBook.
Now I think a balance should be maintained. Everyone has a history and it's nice to see pictures of travels, there's no deal here. But why would you keep pictures of you and your ex being a couple on there? That is the most massively socially awkward penguin thing I can ever imagine. "Yeah, here's a picture of me and my ex, hope you don't mind 'cause otherwise that would be really clingy and protective of you". Uh really?
I know my girlfriend has had sex before and it doesn't bother me - doesn't mean I want her to tell me about the last time she was viciously ploughed! Same goes with exs; I know she's had them, but I don't want 500 of her 1200 FaceBook photos to be of their memories for me to see.
That just tops it off as the most bat **** crazy post here in my opinion! What is this? Treat them mean to keep them keen?!
And again. I've got a photo album at home of my travels in Hong Kong and Thailand with an ex. I would never throw it away. But how socially inept would it be to have it on display around my house?
I'm wondering how many people giving this ilk of advice actually casually have pictures of exs laid around for their partner to see, or have been in the position of having to see it themselves
