Your image isn't in the gallery at present.
Smid must've removed it. Here's the updated version:
Which one was it? When I find a slight error (typically a rogue pixel), I remove it, save the map and then edit the map in the Gallery to upload the new image. Of course, when you save a new image in the Gallery, it changes the extension name, which means all the previous links to it don't work. I haven't deleted any of my maps (I don't think I have, anyway, certainly not in a very long time), but the Canadian one is fairly new and I've been ironing out errors for the past couple of weeks (hopefully all fixed now), so the edits are likely to have changed the link.
I suspect you posted this one?
