Don't fret about your picture being sideways, we can see it just fine. If I click to enlarge it, it rights itself.
You have done a good job on your cards. The picture is upside down because you held your iPhone or iPad upside-down. Check the instruction manual for your device and remember to hold it correctly when you take pictures with it. Your photo software (linked to your device) shows it upright on your computer but if other sites are making it show upright then they must have your permission to modify your pictures using software to do it.
That is not something most of us would like here on Cute as that gives the software total control of the pictures including the ability to crop pictures.
