There's an easy way to email photos integrated into Windows XP "if" your photos are in JPEG format. Left-click on the photo you want to email or "ctrl-click" on multiple photos to select them.



Make sure the "File and Folder Tasks" menu on the left is expanded. If it is not, click on the two down arrows by "File and Folder Tasks". Next, click on "E-mail this file" or "E-mail the selected items", if you have multiple photos selected.



You will probably get a dialog box like below. Make sure "Make all my pictures smaller" is selected.



If you click on "Show more options...", you will get three choices of sizes to choose from. Pick which one you want and click "OK".

Windows will start Outlook and start a message with your photo(s) attached. Fill it out and just click "Send".
