Duplicate photo names

[kwrd]

We had 2 users each upload a photo to the same gallery category. The file 2 photos happened to have the same file name. It appears one photo overwrote the other because now Person A's photo is appearing in both her gallery and Person B's gallery.

How can we prevent this from happening?
We're using version 5.3

You can make sure to use 5.62

Is this a bug in 5.3 - and something that's fixed in 5.62?
