Customer file upload
Adds an customer file upload attribute type.
This extension adds a customer file upload widget to use in product types. When adding a product to the cart the customer can also attach a file.
Please note that as soon as the file is uploaded it is not being maintained. So abandoned sessions might generate clutter on your filesystem. A future release might fix this.
