Regarding the photo orientation, it might be that you have to save them explicitly after righting them. I seem to recall that some smartphones have some issues with cleanly distinguishing between portrait and landscape format.
Are you directly uploading from your phone, or did you transfer them to a PC first? If possible, you might try the latter, open them in a simple photo viewer like Irfanview or Paint, correct the orientation and then save them before uploading them to the forum.
