I would like to remind people that bulk upload to Commons is quite unwarranted in most cases. Really important is that your images are carefully selected for enyclopedic value, catalogued correctly (many people skip this step which makes the whole upload meaningless) and use each of your images in articles. Each image should preferably be used at least once by you in article mainspace.
The current practice of uploading hundreds of images is mostly of little value and essentially a non-activity, unless we do as is mentioned above. Request people NOT to spam Commons.
