You can just go to the bottom like you are going to reply, and then hit he photo button. From there, on a phone, you can click drag or drop, and hit photo library, and upload a picture. On a computer, drop the picture from the photo app onto your desk top. Hit the photo button and drag and drop...
Just add post and upload the photo. It is easier to stay at one thread because everyone there already knows your issue and can still help. I am crossing my fingers for you!:fl
