So alright, I figured it out. To use both types of images, you need to have two separate image lists - each of which has different icon sizes. The ActionManager has more fields for images that I did not notice at first - Images , DisabledImages , LargeImages (this is it!) And LargeDisabledImages . Thus, in order to have full functionality of the tape, you need to save 4 ImageLists.
(I save the answer here for future reference)
