JP, I see your photos are sideways and upside down, I had the same problem if you are using an iPhone and you take a horizontal shot the volume buttons need to be at the top and if you hold the phone upright the lens needs to be at the top. This website is Windows based and won't orientate the pictures from an Apple device so if you hold the phone upside down that is how the picture will come out on here.

It’s pretty easy to edit an IPhone picture. Select picture, select edit and flip it to where you want it.
