Because the XSL-FO interpretation is arms-length from the XSLT 
transformation, one must always express the desired conditional processing 
in the stylesheet before the XSL-FO processor acts on the resulting 
transformation.  An example of such conditional processing is the set of 
"keep" properties.

These needs in particular cannot be expressed in the conditional processing 
facilities in XSL-FO, so you must resort to a scheme outside of the 
Recommendation.

If I had a program that read the dimensions of an image and wrote out a 
small XML instance capturing these measurements, then I would read those 
XML instances at transformation time using the document() function when 
processing the figures and determine in my XSLT stylesheet which strategy 
to follow for the presentation of each image.

I hope this helps.
