Is it possible to change an uploaded image?

Last night I posted this >>1780557. I could have sworn I picked the file with only the bottom-right image, but this one went up instead. I tried uploading that version, but I was linked back to this one, saying it was a duplicate. So, can I replace the image to keep the image number progression going (554, 555, 556 ,557), or at the very least have it taken down so I can post the correct version?

Please report the image, and you can either give us a link to the right one or paste your above description and we’ll help you get it fixed. There’s a couple options - I can’t help you right now because I’m at work, but reporting it is the fastest way to get help with it.
