Uses ImageMagick program to get the width and height in pixels of filename. Sets height to the variable named in height_var in the calling level. Sets width_var to the variable named in width_var in the calling level. I Use ImageMagick instead of AOLserver function because it can handle more than just gifs and jpegs.
