==================================
If you right click an image file and from the menu...
choose...Send to / Mail Recipient...you should
see a dialog box that offers to resize your image
for e-mail. If you do not receive the dialog...

Try this, maybe it will restore the option:

go to...Start / Run and type:

"REGSVR32 SHIMGVW.DLL"
(without the quotes)(Yes, there's
a space between 2 and S)

Click...OK.

A dialog box should report the following:

"DllRegisterServer in SHIMGVW.DLL succeeded"

Also....you can go to the following link and
download and install:   ImageResizer.exe

http://tinyurl.com/36n

Then you can open any folder that contains
images and you will have an option to resize.
Just right click the selected image files and
choose 'Resize Pictures' from the menu. You
can select one image or a whole group.

The program will place the resized copies in
the folder with your originals.
(Tip: *Never* overwrite your originals)

BTW...when resizing if you go to...Advanced
Button / Custom...and enter 640 in each field...
that will be a good size for e-mail purposes.
