First, nice work on the cross - looks great.
To answer (or attempt to) your question re: orientation of photos
I suspect you took the picture in "vertical" or portrait mode, but when you posted it it went into horizontal, or landscape mode.
Not sure what phone you have but if this picture is still on your phone, you can open the picture up in your gallery, or something similar and look at the details. The orientation will tell you what mode it is in. On my Samsung Note 3, any picture in portrait mode is shown as being 90*, and any picture taken in landscape mode is shown as being 0*. Most phones are designed to shoot in landscape mode (think of your widescreen TV). However, most phones are also designed to rotate the picture for you when you view it on your phone, regardless of which orientation you hold the phone in.
Hope all that makes sense. So, not sure if you upload to a computer first, or post from your phone with the photo attached. One way around the issue is to edit the photo, crop it (using the same size as the original), then after saving it in the proper orientation, upload it.
Edit: to add - we were typing our responses at the same time, and I see you are using a Galaxy S4 - your phone has an app called "gallery" - follow my instructions for viewing the details of the photo to confirm it's orientation.
