Vanity: if there is a screenshot of TheGreatDragon on my Wiki, and I made a better screenshot, I would today "upload new version" to upload my screenshot over the inferior old one; it would update everywhere it was used.

With the proposed attribution, my image would be updated everywhere, but still credited to the person who uploaded the inferior version. To avoid this, I would upload the image under another name and edit the pages the old image appeared on to show my new image. This creates a lot of unnecessary hassle for me and for the admin who has to delete the old image.

Imagine the Wikia designers listen to me, and they credit the last uploader. Sometimes I crop screenshots that somebody else has uploaded, or change the gamma to make it look better, or make the background transparent. In that case, my work is really inferior to the original uploader, who should be credited instead of me.
