I have just read Zazzle's newsletter with a list of new products.
Photocards * Invitations & Announcements * Letterhead * Stationery * Flyers * Rack Cards
What are "rack cards"?
I noticed the templates in PNG, EPS and AI - I hadn't seen that before. I always upload images and then make products online. After using those templates, should we upload them in the same format, or would a JPEG work the same way?
