when you type your message like you are doing, you will see a Browse box below the message box.. you click on that, and then it gives you all sorts of options where to get the photo from. if you have the photo somewhere on your computer, just find it, click on it and then click send.
I turned the photo back upright, but the image detail is so poor I can't make out anything... need more pixels... It looks like it could be a Thrinax palm, but I need a close up of the petioles and leaves. If it is a Thrinax, it needs LOTs of light and heat... .and humidity (a hard one to manage indoors).
