What should a convert do with their old Christmas photos?

Many converts will have Christmas photos, in which they will not be observing hijab, be drinking alcohol, celebrating Christmas, eating Christmas ham , etc., none of which is particularly Islamic. However, these photos will also including their loved ones as they grew up, and will be irreplaceable memories, and thus not easy to discard. These photos can both be hard copies, in electronic format (on their personal computer), or on social media (e.g. Facebook, for all their friends to see). **Question**: What should a convert do with their old Christmas photos?
