You normally would provide the artwork that will be printed on the disc surface and/or the dvd case overwrap. For example, there are graphics you provide for the cd image itself, and for any dvd case overwrap graphic or printed insert. These would be in .jpg format.
We also provide artwork graphic templates with all pixel size and dimensions for you to start with.
Edit one of your projects. There are fields in the project edit form that allow you to specify the URL to your .jpg files. We also let you upload these files to our server.
