This is what I scanned and came up with?
If that is the only way it can be done now with W7 and Thunderbird Mail it is a long drawn out process. There has got to be a better, and much easier way to do it. Technology just went backwards about 15 years on this operation if something simpler isn't available.
There is a 'send to email' option in Paint but it don't recognize Thunderbird and I did not see any way to change that. Options are Windows Mail or Microsoft Outlook.
