I'm trying to upload app store listing to the WP8 platform. So I have to upload 1 screenshot at a time and then wait for it to "save" it, which is very annoying, do you know any way to batch upload the 8 images at once? I attached a screenshot of the upload images process below
There's an "upload all" link just above (circled red in the screenshot):
Click on it, select all your pictures and icons, and they'll automatically be put at the right place based on their size.
