How to upload rendering to someone elses project ?

When i use button "Attach the file" next to comment button to upload those pictures the pictures will upload and schow in comments but not in renderings , nor in my "Renderings" tabs. I dont understand why. There used to be button to allow members to contribute but its gone or i cant find anymore and i have no idea why its not working anymore.

They deleted that option. Now you can only share your renders in the comment section.
