If you just have a few photos you want to share—or would prefer to keep Web sites out of it for whatever reason—sending pictures as email attachments (Section 14.3) is still a perfectly fine way to send them around to your friends.

In Windows, right-click a photo file or selected group of files (on your Desktop or in your My Pictures folder or wherever) and choose Send to → Mail Recipient from the shortcut menu. Your email program opens a new outgoing message, with the photo already attached; just address and send.
On the Mac, drag photo files from your desktop onto the Dock icon of your email program (Mail, Entourage, or whatever). Once again, the program is smart enough to get the hint; it creates an outgoing message and attaches the files, ready to send. (You can also drag photos into the body of an outgoing message you've already created.)
If you keep your pictures in iPhoto, it's equally easy: Select a photo (or several) and then click the Email button at the bottom of the window. The beauty of this approach is that iPhoto offers to resize the photos to screen resolution before sending them (read on).
