I know there is a way to easily link to content on other wikis using double brackets ( just W:C:COMMUNITYNAME:NORMALARTICLELINK ) however normally when you want to link to a file/image without displaying it you put a colon before "file:" (or "image:" if you want to be inefficient and waste a character/syllable) to make it a link instead of an embed... but when you link to files/images on other fandom wikis, it seems to function like that even without doing the colon before file.

Is it basically just not possible to do that? It is possible a feature that could be added later? I realize there could be complications arising from that as a possible feature like:
 * viewing the file's page wouldn't tell you where it's being used outside of the local wiki
 * the Special:Images function would only show you locally hosted images, and not give an entire picture of all images embedded on the wiki if that could include external ones

At the same time, I seem to vaguely recall that there used to be spillover (maybe a bug that got corrected) between images/filenames across multiple projects... am I imagining that? Not sure how to find discussions on it if so.
