Product Image Upload and Ordering

Fixed problems uploading product images and setting the order they appear in.

This includes:

• Reliable product image upload

• The order images are arranged in is now kept

How it benefits the Merchant

The first image on a product is used as its cover image everywhere on your storefront, so which image comes first matters. Uploading and reordering images now behaves as expected, and the order you set is the order customers see.
