GIFs have virtual canvas so simple resize isn't usually enough to display correctly in browser. I noticed that you're also trying to send it out with jpeg headers.

What happens if you try this code:

$Imagick = new Imagick();
$Imagick->readImageBlob( file_get_contents(
'http://www.solware.nl/resources/images/solware-logo.gif' ) );
$Imagick->cropThumbnailImage( 64, 64 );
$Imagick->setImagePage(64,64,0,0);
$Imagick->setImageFormat('gif'); 

header('Content-type: image/gif');
echo $Imagick;

Yes, it is working now! Although your code worked, I've 
changed it to:

$Imagick = new Imagick();
$Imagick->readImageBlob( file_get_contents( 
'http://www.solware.nl/resources/images/solware-logo.gif' ) 
);
$Imagick->setImageFormat('jpeg');
$Imagick->cropThumbnailImage( 64, 64 );

header('Content-type: image/jpeg');
echo $Imagick;

Thanks for your help, sorry for the bogus report.
