Carole, thanks for those lovely moth and butterfly pics!
Next time you want to put more than one photo in a message, try this: once you've chosen the first one and its file name shows at the bottom of your message, click on the blue (more attachments) words just to the right of the photo file name, then click on the Choose file button again, then browse through your photos to select the one you want, just as you did with the first photo, and add it to your message - and so on, clicking the (more attachments) words again if you want yet another.
