    Description

      When importing zipped Blackboard 6+ format questions, if there are multiple res000xx.dat pool files within, and they each have image resources associated with them, only the images of the last pool will be used when importing the previous ones. This will mean either broken images for questions from the earlier pool files, or the wrong instance of an image being used if filenames happen to match.

      My patch implements a mechanism for using the correct state for the relevant pool files so that the right images get imported. I've also attached a simple demonstration ZIP to illustrate the problem and the solution.
