This isn't working for me and it is also listed under several community posts. User().Image doesn't seem to show my user image. I have a Office 365 image and it doesn't show up in my PowerApps, or Flow pages online either - it seems some of the products maybe aren't getting the image somehow. Please fix.
Office365Users.UserPhoto (string userId) works fine, but if you have already collected the user profile, then you need another query where i would expect User().Image to be faster.Unfortunatly, this does not work yet.
