Please use the existing category system. Any categories which are not already needed to describe [images, articles] do not belong on the projects. Filter by category, not by image. Thank you.
- For instance: when loading an image for the first time, get both the image and its list of categories, run a string match in the client against the list of reader's 'disliked categories', and decide whether or not to show. the wikimedia cache system could start caching all category data along with image/thumbnail data. Why would that be hard? Notsuohs 20:02, 30 June 2011
