I am no computer wiz but I think I can tell you how to put a photo in your message. Before or after you type your message, click on the attachment icon above (should look like a paperclip). This will let you browse (hit browse) your computer for files. For me, I have to make each picture I want to attach a separate file on my computer before hand(making a file also reduces the number of pixels, DAP uploads are limited to a certain size file). Once you find the file you want you click on it, and it gives you the option of “upload”. that will attach it to your message. You could attach a document in the same way.
