Find the Avatar Section:
First, go to the top header and click the rightmost icon, which is typically your profile icon.
Second, in the vertical submenu, select the profile icon.
Third, another submenu will appear from the vertical menu and select Preferences.
How to Change the Avatar:
Click on the 
pencil icon beside your current avatar picture; a new window with several options will appear:
- System-assigned profile picture (usually a letter from your name)
Gravatar, based on account email- Custom picture, with an upload button on the right side.
1st Method: Using Gravatar
- Go to https://gravatar.com
- Create a new profile or log in with your existing profile.
- Upload the profile picture you wish; it will sync with your avatar once all is set in your profile.
Be careful
The email you register with and the Gravatar profile email must be the same; otherwise, the synchronization with your avatar will not work.
2nd Method: Custom Picture
Recommended dimensions: The image’s proportions should be square (1:1), and I recommend a maximum width of 300 pixels.
Required upload format: AVIF. This open, royalty-free, next-gen format has been proven superior to most other formats for larger images.
If you lack the required software to convert your image, you can use online services like Convertio: https://convertio.co/jpg-avif/
