If you have an email program set up on your PC Pressing the email button 
or using the
File->Send by E-Mail menu command will make Image Optimizer save the Optimized Image to a temporary file and invoke your e-mail program with the file ready set up as an attachment.
You can then simply add addressee, subject and accompanying text and send the optimized image as an e-mail.
Optimizing e-mailed images is well worth while as it saves both you and the recipient on line time and reduces the risk of overfilling the recipient’s mailbox.
