Even if everyone else doesn't uses categories to find images, I do. Organization is much better doing so. Not every relevant image is used on (not many) and not every image is on every page it's relevant to (more likely). I'd rather not go to three pages looking for the image when I know it's in one category. Unless you have a massive amount of images in one category, duplicates are relatively easy to find when they are all on one page.

We don't have a written policy for categories (for main, images, or videos), but it's implied based off our navigation page. I've never had to block anyone for not including categories. I usually just add the category myself and as people start to upload more, they get the point and add them themselves. If there was a written policy, I'd likely treat the issue like any other styling issue (MOS, header formatting, etc) - fix it myself and/or point the user to the correct policy. If they keep ignoring the issue, give a short block and reference the policy again.
