For over 3 years, I have been going thru the hassle of using the PSE7 Editor to resize my HD images, one by one, for emailing.
Here is how to allow the PSE7 Organizer to handle sending, as many as you'd like, after automatically resizing them:
--choose your default email client under Edit>Preferences>Sharing
--select the images in the Organizer
--on the Share Tab, click the E-Mail Attachments button
--using the drop-down menu, select the desired size
--using the slider, select the desired resolution
--click Next
--if desired, change the message "Here are the photos...."
--click on the 2-headed icon to edit contacts
--in the Contact Book dialog, click the New Contact icon and fill in the requested information
--click OK
--under Select Recipients, check the box next to the desired recipient
--click Next
Voila!--your default email client immediately creates an email message
Click Send to transmit all the automtically-resized-and-attached images
