Correct me if I am wrong, but if you have filenames of the form user_nnnnn.jpg, and you rename them to the form user_md5.jpg, the only "loss of data" that could occur is if a user has uploaded the same file under two different names?

Or the 1 in 34 undecillion (billion, billion, billion) chance that the same user uploaded two different files that hashed to the same md5.

Examine what is said, not who speaks -- Silence betokens consent -- Love the truth but pardon error.
"Science is about questioning the status quo. Questioning authority".
In the absence of evidence, opinion is indistinguishable from prejudice.
