I have been trying out the demo site with the Custom Fields for Images and Files and have a few questions:
1) When a customer selects a image(custom field), can the cart immediately upload the file or does the customer have to add the item to the cart?
2) If yes, can the server return information about the image (such as width). I plan on writing a custom PHP script to validate the file and provide the information that I need on the backend. I just need to make sure that the front end can receive an update to the product.
3) Is it easy to add in custom code for price determination? For example, calculating the price based on the material selected and the size of the item uploaded.
4) Can the user go back and update an item with customizations? Right now, if I add a product in the demo store that has options, I can not go back an make changes once I add it to the cart.
Thanks.
