If you are interested in someone else and are trying to develop a new, different relationship with a new, different person then no. Posting pictures with an ex shows that you are still in contact with them obviously but also there's always lingering feelings and your new partner or partner to be could take that as a red flag and be scared off. But if you aren't with anyone new or interested in anyone then hell yeah go ahead, it shows you can be mature and get through difficult situations and still come out strong.

I don't keep in contact with exes. It just complicates future relationships. I've no need to keep in contact with an ex. I usually to cut all ties and move on
If someone is in a relationship and they hang out alone with an ex , and post pics of them together on social media they are crossing a relationship boundary. That would be humiliating and disrespectful towards their current SO.
I'd never jeopardise my current relationship for the sake of hanging out with an ex. My boyfriends feelings and position in my life would always come first
