Is that a known bug ?

Hi dear support,

I want to share something I discovered today.
I have several users and thanks to your plugin I added their picture.

All works fine (and thanks for your plugin).

Today I needed to change my user language setting (from english to french).
If I do that, then all the users picture are reseted (to nothing). Note that all pictures are (and will be) added by administrator and not the users themselves.

Even if I come back to the previous language, there’s no more the users pictures.
I need to add them manually one by one.

Is that expected ?
Thanks for helping.
