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
