Anyone know how to "digitize" or what the heck this exactly is? I want to order a few custom items for my bus. (hats, duffle bag, etc.) and they all require the file or picture or whatever to be "digitized." They all can do it for me, but it's like $75 to have my file/image digitized.

What exactly is this? And is there a program anywhere that I can do this? Is this even something you do on a computer? One of the vendors that I'm going to get my hat from said I can bring in the "digitized" version on a CD, so this makes me think it's done through a computer somehow.

So again, anyone know what this is and how I can go about doing this?
