Upload image to commerce product on save?
I installed Commerce Customizable Products and created a new line item type. This enabled me to create another product type with an upload field in the add to cart form users can use to upload file to the site. Also use rules obviously to do some more backend stuff, like change file location (that's set with a token uid) to be updated on username change and lots more. Can do lots of fun stuff with media/file entity, but your fix also works, just adding this for the search bot arena ;)
