There is the macro \getfiguredimensions which, amongst other things,
sets up \noffigurepages, \figurewidth, and \figureheight.
Here is an excerpt from a macro I have been using since 'forever':
\newcount\imgcount % to store the number of pages
\unexpanded\def\addimage#1{%
\getfiguredimensions[#1.pdf]%
\imgcount=\noffigurepages\relax
\dorecurse
{\the\imgcount}
{\getfiguredimensions[#1.pdf][page=\recurselevel]%
\ifdim\figurewidth>\figureheight
...
\fi }}
Best wishes,
Taco
