How to change the picture in the upper right corner in Gmail? The solution should work in all the (major) browsers.
I usually keep opened several Gmail accounts in various tabs at the same time and it would be easier to quickly distinguish them.
I am not asking how to change your profile picture, I have done that:
However Gmail still uses just the fist letter of the name.

Click the icon that you marked red and click on change. You can upload a picture in the popup or use one that's already in your account. Screenshot
Edit I also had to do a "hard refresh" in Chrome (Ctrl + F5) for the correct image to be displayed after visiting the site again. Before I did that the picture changed after I uploaded it and reset back to the letter on refreshing the page / visiting it again.
