If you are finding that your pictures taken with your iPad are uploading sideways or upside down, you can avoid this by taking your pictures holding your iPad horizontally and with the home button on the right hand side.
I've had similar problems with my iPhone. I usually end up emailing them to myself then download and flip them on the desktop computer if I need to post them.

Any "i"device or even most new Android phones (my S4 is included in this bunch) the menu/home button must be to the right. For pics and video. Everything is a "Wide" format, so it should be taken as such.
