Upload of Images as Option

Hello,
Here is my problem: Customer should be able to choose an option for upload a Picture (which would change a price).
I have created a Item custom field, and it works. But I need a option to deactivate this option (Checkbox or Dropdown could be nice). Is there Any solution for me?
Many thanks

Hi,

There is no automatic solution that you can just configure. But you can add a line of javascript to your product page to add a javascript event on the dropdown selection in order to hide/display the custom field area. You can add your javascript in the file "option" of the view "product" via the menu Display>Views.
