GiftRocker captures a number of images for each shopkeeper that are used in emailed gift cards, ordering pages, texted gift cards and Passbook. Some of the images are managed with the company profile and some are managed within themes. Note that you may have separate themes for unique offerings. For example, a wine dinner hosted with a local vineyard might require a co-branded theme just for that dinner. In this case, you may first copy your default theme and customize with both logos or an appropriate background.
Edit the shopkeeper profile clicking to Profiles / Shopkeeper Profile. Click  to edit. Change your default theme by clicking the Edit Theme button within the Shopkeeper Profile view page.
Here’s a list of these images and their sizes to help you manage your shopkeeper profile.
