The admins/mods don’t delete pics without first informing members and asking them to fix the problem, so this has to be a technical problem of some sort. To solve it, try this:

– Go into ‘My account’ and then click ‘Change your info’

– A few lines down, it says ‘Avatar’ and if you do have an avatar connected with your user name, then it should be displayed there. You likely have no pic there, but even if you do, try clicking ‘change avatar’ and then select the one that’s yours.

– If you don’t remember the name of your avatar pic, then you’ll probably not be able to find it. In this case, upload it again (under a unique name you will remember) and then select it from My account/change your info.
