I am using Magento's file upload on the front end for customers to upload pictures. When I get to the cart, it shows the product image and not the uploaded file. What do I need to add to get the uploaded file to show instead of the generic product image? Thanks.
There are two ways.
1) When you save image from front-end then it will added to the particular product image gallery and set this new image as a image ,thumb image so all places you got latest uploaded image.
2) The another way is that if you don't want to add in image gallery then create your custom module. Crate one table and store the product id,image name. When you required this product image then fetch from our table display over there.
