But you still have to specify a size for the image. It can't be "any"
width. The cropper needs to know the ratios. It needs to know what
size width to scale the resulting image created to. HEADER_IMAGE_WIDTH
must be a number, not a percentage.

See, a "header" is generally a single image across the top of the
site. That's why it's called "add_custom_image_header" and not just
"add_custom_header", because it's not a tiled background.

If you're wanting to do a tiled background in some fashion, then I'd
say to not use the custom header functions at all, as that just
promotes end-user confusion. Do something totally custom instead.
