I guess it depends on whether the images are related to elements of the story 
list. If you need to force something on to the same page as another flowable 
then you should probably use a flowable with zero width/height (it also needs an 
attribute _ZEROSIZE=1 to force some things to take notice of it). Paragraphs 
already have a mechanism to allow user code to execute (the onDraw tag) so 
perhaps that might also be a possibility. If it is page furniture then it 
probably ought to go into the template.
