Can images, that are attached to items, be printed on the Traveler?
Item images can be stored against items under (Inventory > Stock Items > Additional tab) by double-clicking into the whitespace on the left side of that screen. Generally, these attached images are used for reference in this screen only.
That said, though, it's possible to have them print on the Traveler as well. If the image is to print on the Traveler, it needs to be a thumbnail size image no larger than 512 x 512 pixels. Otherwise, it may be difficult to see.
If you need an image larger than thumbnail size for manufacturing reference, create an image document and link it to the item in the Documents tab. Images attached as linked documents will not automatically print on or with the Traveler but must be retrieved and printed in the Job via (Jobs > Jobs > Header tab > Additional side-tab).
