I would prefer, as UX, that it would follow this order: - First load first frame on lowres (may be so lo that is blurred) - Then add a small rotating loading icon on top of image, possibly with a notation that is a GIF - Then load first frame completely at correct resolution - Then load all the other frames in the background, only showing me the first frame still - When all frames are completely loaded, remove loading rotating icon and run the GIF normally.
