(Just about) Everyone updates their character at least once every week or two. This means that people are having to continuously upload new user images to their articles. This indeed, results in a very large Image collection on the wiki.
Recently I tried to experiment with the infobox to make it so it automatically updates the user profile image whenever they update their character in real time. Unfortunately, a lack of wiki-text knowledge and ROBLOX not being on Wikia's 'whitelist' meant it was not possible.
So heres a way to update user images without having to add lots of individual images to the wiki everytime they update their character. Instead, you will just overwrite the old image with the new one. In the below example, I will update nottinghamftw's user image.
