It also depends on what application you are using to access your email, whether or not it will allow you to attach an image to an email and send it.
Some email programs will limit the attachment size, or limit the attachment file type. So it kind of depends.

Also, There is a default application already on the Samsung device GT-S7500T for using Email. It is simply called EMAIL. YOu would use this for a Hotmail, or a domain you own, or yahoo. Also, this default Email application, DOES allow you to attach files or images to email.
