Is it weird to keep pictures of my ex and I on my phone?

Like if I was dating a woman and she asked to see a picture of my ex wife and I showed her like 5 pictures of us together is that too much to keep?
Would it be intimidating or appear like I’m not over the relationship?
We were just together for so long and I have some pictures that I really like, should I just delete them?
How would you react if you were dating someone and they kept 5 pictures of their ex on their phone?
