Multi panel print software?

[denci]

I see a lot of photo printing shops advertising multi panel canvas prints.
I would like to look into have a one done, but I don't like the idea of going through all the hassle of uploading a print and trying to manipulate the photo online.
Is there any software out there where you can preview and edit a photo as it would look like in a multi panel print.
Thanks for any help.
