How to Add Graphics To Ticket Design?

My museum wants to add our logo (a very specific font of our name, nothing crazy) to our credit card receipt template. 

The ticket design aspect I totally get, you just click the Graphic button and plug in what file you need. My problem is I don't know how to get the jpg file of our logo into Tessitura to be able to pull it into that graphic. 

Can anyone explain it (in plain English) because the Help System is not helping. Where do I save it to so that I can pull it into the correct place?

Thanks!
