By the way, it is common for forums to operate this way regarding photos and videos. While you can place a link or display an image in the forum, the photo or video needs to be stored somewhere else on the web. So the forum provider does not bear the cost of “serving” the image. Of course, Weta could provide the facility of storing images if they thought the cost was affordable. And place limitations on size of image acceptable. NZers are know for their generosity, so who knows what might happen!
I’m sure their IT staff could provide more detail.
