It depends; if the GIFBUILDER's parent object is an IMAGE, then yes
you can get the size:

"The array $GLOBALS["TSFE"]->lastImageInfo is set with the info-array
of the returning image (if any) and contains width, height and so on."

The same information IS determined by the core when using
IMG_RESOURCE, but it is not retained. I've requested this as a feature
addition, but I don't think it's made it into the core yet--if it'd be
useful to you too, maybe add a comment to the bugtracker:
