How to copy
There are a couple of ways to copy pics imbedded in email.
The easiest way is if the picture originated on the internet you can click the pic and go to the host site. At that point just right click and save to your docs
Another way is to right click and copy the pic. Then open a photo shop application, choose new image and paste the pic. Then save as a jpeg to your docs
Once the pic is in your docs you can upload it to .net or any other hosting site
