A template based design is one in which an image is required as a product template to give a visual effect of the actual product to the customer during the design process. For example, TShirts, Mugs, Phone Casing etc are all template based designs because they require a product template unto which the design is placed, but not printed in the final output. A business card is NOT a template based design since we really don’t need an actual business card to be displayed in the design window.

This module basically allows users to change the template image at design time without going outside of the editor. So for this example, we will consider a TShirt design where you will like the customer to try out different T-Shirt colors from your store to see which is best for their design by simply clicking on a color pallet.
