It doesn't use more bandwidth than normal images, as PHP/GD is completely server-side. The image generated by this script is 3,4 to 3,7kb large as you can see by checking its properties.
Utilization of the GD library takes up some extra server-side system resources, but the GD functions used in this script are few and very simple.
