I don't think he's keeping them to remind him of you. More to do with the physicality of them.
Don't think his new gf would be too happy about that.
I doubt he's trying to make you jealous though, probably just genuinely thinks the photos belong to him and doesn't have the decency or the respect of you to delete them. Either way he's not worth another thought. Move on!
