Database: Linking to a group of URLs in one cell rather than uploaded images??

I’m getting a CSV file from a vendor and have to turn it into a product website. In their CSV file, the images they associate to each product come as a list of URLs separated by commas all within 1 cell. Here is an example of just one URL in one cell (usually there’s 6-8 image URLs in each image cell):

https://media.sandhills.com/img.axd?id=4077155527&wid=&p=&ext=&w=588&h=784&t=&lp=TRK&c=True&wt=False&sz=Max&rt=0&checksum=rvxB8E6hzFKzAzW7%2fTPYsVJKm9Hjyq0I%2bTZuD5ddZhG0JhqFS09bWZAARiDH2FUBPKdlY5U1XcLtpvMucFnMdtjajT41OcQja97vxDg0TdGKmXaheKiD23t6HD%2fxID55

As you can imagine, when I go to link up a dynamic gallery to the dataset column that contains all these URL groupings, it won’t let me link up. 99% chance if I can’t figure this out I’m dead in the water.

Any crafty ideas?? Please help!!
