I can only post from my iPad. I don't know if it works the same from a phone. I take the picture with my iPad and it goes into my camera roll. I then use the iPad to Google quiltingboard. Once I am logged into quilting board, I start a new thread and when I want to add a picture, I use the little paperclip (manage attachment)to retrieve it from my camera roll. If I am adding a picture to a thread with the Quick Reply box, I use the little tree icon on the top of the Quick Reply box.
