Good morning, I need help with setting up a way for customers to customize their product within the website. I have created a form. However, if they want a picture they will have to email it to me. I do not want that. I need for customers to be able to tell me what they want on their item as well as upload their logo at the same time within the website. If they have to leave the website to upload the photo I'm afraid this will deter them. PLEASE HELP! Also, I am struggling with linking categories. I have watched several videos and its not working. The category link takes the customer to a blank page. When I add the product to that page it then shows up with all the other items on that page, not in a category on its.
