It doesn't work for the same reason "cat image.gif" doesn't work: you can't just print a binary file format to the terminal and expect it to show an image.

Just send the file data to some program that will display the graphics, for instance, if you have image-magick's display program installed: 

use LWP::Simple; 
open CMD,"|display -" or die "Can't fork display program: $!";
print CMD get("http://www.nhc.noaa.gov/storm_graphics/AT06/refresh/AL0
+606W5+gif/144631W_sm.gif");
close CMD;
