I am opening it in the Jerboa app, the browser is opening what it's being told to open, I assume? That's not the full size images. On kbin you can get both the thumbnail and the full size images, look at the connect app, it shoes the full size images (and then crashes due to running out of memory)
I'm sorry, I'm not exactly understanding the problem yet. In the gif i can see you open the images. Is the problem that u open the lowres thumbnails and not the actual images? Bc I don't think it does that. I did notice there is apparently a limit to zooming into a image.
