Save your pictures to the MY
PICTURES folder. Click on the picture, or hold down the ctrl button and
click on up to 3 pictures with your cursor, and then you can send the
pictures to Outlook Express.
On the left side of your screen
you should see some options. Choose "Email the selected items" under the
"File and Folder Tasks" heading.

You will get a dialog box where
you can again select options. The screenshot below shows that "Make all
my pictures smaller" option is selected. Clicking on the "Show more
options…" link will expand the dialog box to include different file
sizes you can select. Clicking the "OK" button will start the process of
attaching your files to an email. It will open your default email
program and attach them to a new email. You will see a message that your
files have been attached and are ready to send. Fill in the rest of the
email information and send your email! (Use the "Keep the original
sizes" option if your pictures are already the correct size.)

This will automatically attach your
pictures in a perfect emailing size to a blank email and then you can
address it and send it. I have many photo editing programs, and
this option isn't open to me anymore, but you should have it. The
trick is to save the photos to MY Pictures folder. Check your pictures
in the sent items after you send them and you will see how great they
look.
