Fixed to where a primary product image is no longer required as a populated upload field to upload an additional product or non-product image. Updated the 4 additional product image fields to upload new images to the product's ID sub-directory without resizing (as-is). Added 2 fields for non-product related images to be uploaded to the main images sub-directory. Misc minor typo/fixes included as well.
