I hope I am not getting something wrong here...

I notice that in my profile, I am listed as the owner of the team Microsoft. That must be because I created that team in a number of projects I signed up for if it didn't already exist in that project. Eventually, I must have become the founder in most of the projects, but definitely not all. Anyways...

I look at the team profile, and don't like the default picture.

In the meantime, I notice the Team founder link on the left of my screen. I click it and see the Team profile link. I click on it, and see an Edit button. I use that to add a 10.9K profile picture, change a few of the selections, hit Save, expecting that things will be saved.

Nope. Nothing gets saved. Still no picture, and all the selections are back to what the defaults were.

Am I doing something wrong?

Fixed.

Now I can edit the selections about emails etc., but still couldn't attach a 468x140 10.9K JPG.

Interesting... The picture I tried to add 10min ago and didn't look like it worked shows up now. So, fixed, but the immediate feedback to a change in picture is missing.

So I just uploaded jpg and png logo's to your team profile with Chrome and Firefox. Works as it should.

Oh, so that was what you had uploaded that looked like what I tried to upload. I was wondering why a few white rows were missing at the bottom...

I tried to upload mine again, and it worked now. Your pictures must have cleared some clog in the pipe...
