Uploaded pics turned sideways

Thread starter #1
I haven't posted in quite a while. I tried to post some pics and they are turned sideways. I took the pics with my I phone 6 resized them; and uploaded them to my computer to a folder. I then tried to upload them to the Forum and they turn sideways. I even rotated them thru editing; and they still turn sideways when I upload them. Could someone tell what is going on. Thanks
