Once you've created your print artwork (footer graphics and/or overlay graphics), then you can easily upload them to your Photoboxx account. There is a convenient place for you to upload your artwork in order to be available on your account so you can select it when you are starting your event.
See below how and where you can upload your print artwork on Photoboxx:
Upload your artwork. Adjust your file if needed, then click done.
It should now show up in the specified print artwork section.
You can add more footer or overlay graphics. All graphics will stay stored here.
When starting your first event, your artwork is now ready. You will select the graphics when setting up the event.
