^ Essentially what Rob up there said. Two main things that are important with images on the wiki are (1) being named properly and (2) being categorized properly (assuming the images are of good quality in the first place). Unless the filename of the original is garbled or nonsensical, it's best to upload over the existing image.

If it's an identical filename, the new image will just show up as a revision on the old image, while the newest image will be shown on articles, posts, where it's used, etc. so no harm done there
