Have you ever asked yourself at the end of a letter with Word, or an e-mail under Outlook, how best to sign the document? Because just putting your own name under it is of course not the same
Presumably, you have already come up with the brilliant idea of simply saving your own signature as an image with a transparent background on the PC, and then paste it into the document or the e-mail as a picture. Of course you can do that, but in most e-mails this will not do you much, as e-mail programs often do not display images for security reasons by default.
And this type of signature is also not trustworthy, because forging it is very simple. It looks good, but the bottom line is nothing more than a placebo.
