hay there
I looked into how you can fix up the whole rotated art post problem some of your posts have been having and there are some things that could help fix the problem
1. put your images in a image software like MS paint and change the resolution a little bit and save it as a new file (Jpeg or png) and us that one to post
2. if you don't have any computers you can try to change you camera settings and see if there is any settings that may effect the photos orientation, like portrait framing or something

other than that I don't know how else the problem can be solved, Newgrounds on mobile isn't used as much as it is on computers so if you're super stuck, maybe the art forums could help if you ask
