Update on tags: I've fixed the "cake" tag so that it is now a direct child of "food" (images of cake didn't appear under food because it was a child of "sweets" instead)

Our newest tags are "boat" and "wheelchair". The "vehicle" tag was getting very messy, and "wheelchair" is an easy, inclusive object tag.

Please check your old images carefully for "wheelchair" images, though "boat" should be sorted out in a few days without much help (everything is already under "vehicle" so we're going through them page by page). Another note though: you have to be able to tell it's a wheelchair from the image.
