Yes, archiving them somewhere. I think this is highly individual. For me, right now, I feel like there can be catharsis looking back at those old photos. When I was first transitioning, especially a few months into HRT, it was a major confirmation for me that looking at old photos of me and comparing them to how I looked now I could distinctly tell the old photos were not “me”, that I couldn’t recognize them as myself in the photo, it looks like a stranger (even though I felt not all that much had changed, merely the presence of a denial / neglect beard and masculine clothes, etc. in those old photos were enough to create that distance).

I wouldn’t want anyone else to have photos of me, though. I think I would want to control when and under what circumstances I come across them. (That has always been true, but now I feel more justified in that position, whereas before I think people just thought it was something unusual or unhealthy about me.)
