Found this going through my old camera roll and liked the perspective. Posted as a link because image posts are failing for some reason.
Picture worked (and worked well) in the end. Commonest cause for me is that there are file size (or possibly simply pixel number) limits in Lemmy. From time to time I have to resize the photo to get it posted. If you are lucky the "broken upload" image in Lemmy contains a hint of the reason.
