I have really old technology and it's easy for me to post pics. If you have a photo archive on your phone: Create a post, then click on the "attach files" button. You should be directed right to your photo archives. Select one or more pics and they will be uploaded as thumbnails to your post. There will be a button to post any or all photos as full size. Post to thread. That works for me. I forgot to add that I'm an old stupid guy, so if I can do it, you should be able to, also.
