How can I change the default thumbnail size for image galleries?

There are three sizes of images that are possible in an image gallery:

  • The originally uploaded image size
  • The medium image size
  • The thumbnail image size

How are these sizes used?

  • The thumbnail is used as a preview of the image in the slideshow
  • The medium-sized image is used in the slideshow.
  • The original image can be shown as a "view full size" image.
