Don't know if this would work for the person asking. But what I do is save the screenshot to the desktop or someplace else I can easily find it,
double click to open it first, then do a right-click copy on what appears in PhotoViewer. That image can then be pasted into a standard e-mail as a visible graphic embedded in the body of the message.
In most e-mail clients I'm familiar with, just doing a right-click copy
without opening it first, will load the screenshot into your email message as an attachment. Same goes for using the copy to clipboard button in SSC.
