Tkinter is dynamic by definition.
So you just need a loop to add your images in some kind of collection 
widget. A Canvas or a Frame would seem obvious choices... Just choose 
your preferred layout manager - simple pack() would work or you could 
use grid() for more sophisticated shapes.

You can certainly embed images in Text widgets, I'm not sure about 
Labels, but I think you can. You can also use Buttons.

That doesn't sound cumbersome to me, it sounds like standard Tkinter 
practice. Frames are the base object of nearly everything in Tkinter.
A Celtic cross pattern could just be an algorithm for positioning things 
on a grid... So it may simply be a case of having different generator 
functions for the card locations (a list of tuples?) and selecting a 
function rather than a Frame.
