====== Adding invoice images ======

Adding images to invoices will make shipping easier, reduce mistakes and help customers identify what the heck it is that's in that box. Since zen cart already has images for all items, its really easy to add

{{:zencartmods:invoiceimage.gif|}}


By default, it will use the thumbnails used in the shop navication. Optionally, you can make a folder in images/ called /invoice to override the images in case you'd like a different image on the invoice than shows up on the website.
