can't delete my profile picture on icloud.

@_oplkj_ Unfortunately, like most online profiles today, once you place a profile picture, the only way to remove it is if you have a replacement. May I suggest quickly plugging this grey photo from google images in there, or perhaps something more visually appealing if you feel like it.

Is there an issue you having any sort of profile picture at all? You could always fake it with this "user image icon"

Good luck, and to @tygb good advice.

You can edit profile picture from system preferences > iCloud change the picture and click on save , restart the Mac after few minutes sign in with account credentials at www.icloud.com click on account settings you will see the profile picture that you saved .

In Mac OS Catalina > system preferences on the left of window you can see profile picture ( if it is empty click on edit and choose desired picture and save it ) .

In system preferences > profile picture click on edit a window appears , many options are seen moments , collections , years ....click on drop down arrow of each , in reality the pictures are saved in main photo application of Mac .
