Okay, so I have 160 SVG files, one for each of my playing cards (yeah, I know I should have explored a template approach, but that's hindsight now).
A bulk of the 160 have a moon image on them as a background. The moon image is centered on the card and takes about about half the height of the card (if measured from the bottom) and extends to the printable left and right edges of the card (so there's a bit of a border on both sides). It's a perfect circle.
Now I need to replace these stand-in images with art provided by our artist and need the most efficient way of replacing the image with this art, but also having it end up in the same spot and almost exactly the same size on the card as the original.
What's the best way to achieve this?
Thanks!
