Well the ipad explains the photos. You're holding it upside down (as far as other computers are concerned) when you take them. Ipad automatically remembers what direction it was when you took it and shows it to you right-side-up. Iphone is the same - if you hold it with the shutter button top right, like an actual camera, the photos are upside down on Windows.
To delete photos from your gallery edit your spark page first, then click Edit My Gallery.
