how to use mogrify to resize image

[ppowell]

I'm sorry, FIFTH question of the day:

		 $mogResponse = exec("mogrify -size ${width}x$height " .
				                  $this->locationPath . '/' . $this->fileName . ' -resize ' .
				                  $width . "x$height > +profile " .
				                  $this->thumbLocationPath . '/' . $this->fileName . ' 2>&1'); 

This attempt at creating a thumbnail only causes the original image to be resized while creating a "ghost image" in the /thumb folder where the thumbnail should be.

Could someone show me exactly how to use mogrify to generate a thumbnail in another folder while keeping the original image intact?

BTW imagecreatetruecolor() is not an option in this case because I'm working with PHP 4.1.2

Thanks
Phil
