o wow.... i thought everyone knew how to do this xD.
Well, theres a bunch of ways to transfer your pis onto the computer. The easiest way is to connect your computer by using the USB port on your camera...if it actually has one. Then your computer should be able to recognize it and open up and explorer window. There, you should be able to see all your pics. All you have to do is drag them onto your HD.
Now, if you wanna mail your pics, theres not much u have to do. Most e-mailing sites give you the option to attach a file. Just browse through your computer and attach the pic u wanna send.
Finally, if you wanna upload pics onto the net, theres tons of sites that can do it for you for free. I prefer
