Make sure you know where your photos are filed (e.g., My Pictures in My Documents). When you write your email, there should be a paperclip icon in one of the toolbars at the top of the window. Click on that, and click the Browse button. Locate your photo, and double-click it. The filename of your photo should appear in an Attachment bar space at the top of your email. Now you can either repeat the procedure to send more photos with the same email, or just click on the Send button to send it.
