Before diving into the details, take a look at selecting Import Records using the folder option. In a test table see if you can pull all the images from one folder into accontainer field in this table as "references " to the image files. Note that you can put the file name into a text field at the same time.
Report back on your results and we can then discuss how to modify this practice task to do what you need. If your image files have unique file names across all stamps in your collection, this will be easier to do.
