In order to share pictures you need an online link to you pictures. If you have your pictures automatically uploaded into the cloud, great they're already online! All you have to do is to right click the image and choose "copy image address", that's the link you have to paste into the "URL" line when clicking the image icon in the message box.
If your picture is only saved on your phone and not online you need to get it online, this can be done by for example uploading the picture into google drive, dropbox or any other cloud you might be using. After that just follow the steps I mentioned before.
Sometimes you have to be a little bit naughty.
