https://www.thcfarmer.com/community/threads/still-need-help-with-avatar.46509/ , and
https://www.thcfarmer.com/community/threads/how-do-i-upload-a-avatar-photo.49335/ and so every one's up to speed from the other thread here's what I said to try.
ok drag the mouse over the user name in your upper right corner with out clicking , then scroll down to personal details click on that. then scroll down a couple of inches . it should say edit avatar push that, and then follow the prompts from there .otherwise you might not be able to yet...
it kinda sounds like your doing what I said but it isn't working for some reason.
..
And the instructions I gave you worked for me , when you get to edit avatar click on it then it will say browse . Push that ,it will open a window from your computer .This window should say chose a file to upload , and pictures under it. Click on the picture that you want , and then push open in the bottom corner. At that point you should see your avatar , beneath it says okay push that and you should be done.
