Here's a quick guide explaining what kind of product photos you will need to build your customizer.
Resolution
You will need high resolution photos of your product. As you cut out the different customizable areas, you need to be able to see the details clearly. Once you are done, you can resize your final images for web to approximately 1200 x 1200px, 72dpi.
Color
If you are planning to apply colors dynamically on your product, a lightly colored product usually works better. Avoid black or dark colors if possible.
Views
You need one photo for each view you want to show. We recommend 1 to 5 views.
