Does the wiki in question have DPL enabled? If yes, you can use something like the following:

Start the offset once at 1000 and once at the total number of images on the wiki and bisect it until the list shows only a small amount of results. Offset + number of results is the total amount of uncategorised images then.

PS CC has currently the astonishing number of 16441 uncategorised images :D
