This one I don't get at all. They even admit that it's "the webmaster's responsibility to prevent unauthorized remote loading of images" so why are they getting involved?

Because people who do this can be a pain in the arse? Basically, it's the 'Slashdot effect' writ smaller; if you link to some remote image in a context in which lots of people are likely to access it, the person hosting the image gets charged for all the bandwidth used. Now maybe that's OK if the image is a public one that people are supposed to link to (or at least the page it's on), but if it's some random personal image, not so much. If you want to show it, surely netiquette is at least to host it on your own space.
