I am looking for a shopping cart system that will allow a user to upload an image to the product (t-shirts). If there is a cart that can visualize the image on the item, even better.
Try with AJ Shopping Cart Software which is the most user friendly feature rich shopping cart software to create your online store.
Try www.ezOSC.com all of their shopping carts have WYSIWYG (HTML editors) on the product description pages. Very User friendly software.
Oh ya. The WYSIWYG editor also allows you to upload images and gives you a visual before you approve.
Just to make sure everything is clear, I want the person visiting the site to be able to upload their image, see it on the product and order. Similar to www.canvasondemand.com
you can get your own ads space from ZSCART - saas ecommerce solution. It will let you upload your own products and prices easily. simply monthly payment. Try it out.
Ah now I get it you want the end user to be able to upload a pic and view it on the product. I am sorry that I didnt understand in my last responses. This is most likely going to be a custom job. I have only seen this feature on a few shopping carts and each one is done through custom programming. I dont know of a shopping cart system that does that stock...... You will want a good programmer for this job. That is also going to be I know the guys over at ezOSC have done this for one of their custom osCommerce builds, but again it was custom. Good luck to you.
