Adding img_id and oi_img_id edit
You may be interested in bug 71198, which would add img_id and oi_img_id. That way, you could do a prop=imageinfo query that would grab the image info for, say, 500 or 5,000 images, which you would specify using an imgid parameter. Later, of course, it will be a prop=fileinfo query. Leucosticte (talk) 19:43, 24 September 2014 (UTC)
