now it's been tested - i used the one off phpbuilder:

|$frames = exec("identify -format '%n' theimage.gif");
if ($frames>1) {print "This is an Animation!"; exit;}

it works perfectly - what gives is i'm setting up a site where folks can 
upload images, buddy icons, etc. I will use convert to resize them.  
Earlier I found some 'convert' code that will resize an animated .gif 
and not make it split into separate layers. With the ability to test the 
file first, I can use the leaner version on single layer images.

this is great.  thanks to both of ya. -bob
