SPUG: GD file save

Dear Perl Gurus...

I used the GD graphic module with success on a couple of projects last 
year to create charts from live data and then both display it directly 
and save the GD generated image to a file. That was accomplished on an 
NT system.

I changed over my server to Linux last September and have had excellent
results with the exception of this strange GD problem...I cannot get
the GD module to save the created image to a file on the hard drive. 

Following lines are based on instructions with the GD module...

   	###print to screen  -- this works
   	binmode (STDOUT);
   	print $im->gif; 

	####write to file -- from my NT module docs, works on NT
	$imgfile = 'testsave.gif';

	####write to file -- from Linux module docs, does not work
	$gif_data = $im->gif;
	open (MYFILE,">testsave.gif") || die; 
	binmode MYFILE;
	print MYFILE $gif_data;
	close DISPLAY;

Neither of these "write" routines will create/save the image. I have
chmod and owner/group names set correctly to allow file creation.
Anyone know what I'm missing with Linux/GD?

Thanks in advance...
