I just bought SnagIt for Mac a few weeks ago.

One of the things I use SnagIt for is taking screenshots of e-mails that I wish to post on my website.

Because these e-mails are sent to me, I need a way to complete remove my PERSONAL E-MAIL before I either save the screen-capture as an Image (e.g. .png) or as a PDF.

Is there a way to be 110% certain that some whiz cannot reconstruct the original screen-shot using something like Photoshop, and thus exposing my e-mail??

I played around with SnagIt's Erase and Pen tools, and then used "Flatten", but I am uber paranoid that my e-mail is still hiding underneath things somewhere...
