How would that work in regards to the person who originally uploaded the image, would it be removed from their uploads? Or would it be attributed to two uploaders.
That's the question I'm asking: should the uploader be kept or changed to the person replacing it? Having two uploaders isn't possible, it has to be one or the other.
Renim suggested changing the uploader, since technically they're not who uploaded that exact file any more. Thinking it over, I think the uploader should stay as is, since losing an upload could affect your deletion ratio and hurt your upload limit. Also I think people might get salty if they lose credit for things they uploaded.
