So I’m trying to upload a higher res version of an image of celestia but it won’t let me because it tells me that it’s already been “uploaded” and that it’s image #2155253, which is a different image of nightmare rarity. How do I fix this?

Well, I guess you should buy some lottery tickets, then… The “exact image” block is based on a mathematical formula derived from the image, the chances of two different images having the same resulting value is astronomically low.
