One of the ways is select “Upload a File” and it will give you the option to choose a picture saved in your “photo library”, or you can “take a photo” or “choose a file” . “Add” the picture you selected, then you can select “Thumbnail” or “Full Image” - then hit “Reply” That’s it, all done.
Well it's true lol, as Steven Tyler said " you ain't seen nuthin' 'till you're down on the muffin"... words I live by lol.....
