If you are sorting your records for this report and have a field with a value that is unique for each record...
Add a "print below" sub summary layout part, "when sorted by" your Unique value field.
Put your container field into this sub summary part and specify in part setup that the part not be allowed to break across page breaks.
Then add this unique value field to you existing sort order as the last field in the list of "sort" fields and sort your records by this new order in order to make the added sub summary layout part visible.
I set up subsummary with container associated with workID. Container images appear when not in Preview, but disappear entirely when in Preview. I must be missing something. Here's a screen shot of layout, part setup, & subsummary part definition. I found nowhere to specify "print below". Report is sorted on tour order & artworkID, latter being the ID for container image.
