Another way for you to send pictures between your friends and family is to e-mail them. Your cell phone has to have e-mail capabilities for this to work, but a lot of the phones these days come with that ability. You can e-mail them to other people or, as mentioned above, to yourself. You just have to type the e-mail address in the To: field just like you would if you were using Outlook Express and it will be sent.
If you see something while you're out and about that you just have to take a picture of, you can snap the photo on your phone, send yourself a quick e-mail and when you get home, the picture will be on your computer waiting for you. You can then send it off to other people or do something like set it as your desktop wallpaper.
