Here is a quick tip that will let Microsoft Windows automatically reduce the size of your photo
before emailing it. This assumes that you don’t have any other image editing program to edit
the image (Photoshop, Paint, etc.).

In order for this to work, you have to be sending the email from your computer using Microsoft Outlook, Outlook Express or Thunderbird:

1. Browse to the location where you have saved the original picture that you want to email.
2. Right-click on the image file with your mouse.
3. Select "Send To -> Mail Recipient"
   
4. In the next popup box, select picture size and click attach
   

Depending on your default mail settings, Microsoft Outlook or Outlook Express will then open and your automatically compressed picture will be attached to an email ready for you to address and send.
