Thread:Project:Support desk/'Hiding' links?

This might be a silly question, and so on, but I thought I'd ASK at least... Is there a way to make a page a part of a category, but to hide this fact on the page?

We have about 100 pages that all should have an image, different for each. However, about 30 lack images at the moment, and more pages are coming up faster than the images are shot. Is there any way to make these 30 part of a category, so they're easier to find as the images get taken, without the page having a link screaming "we're lazy bastards that can't be bothered getting around to taking these pictures!" at the bottom?

It isn't that important, per se, but it would make things easier and nicer.
