I am trying to create a system of outgoing and incoming e-mail, and I do not want my picture to be placed on outgoing mail that I am saving as a pdf. These pdf files might end up being used as evidence in court, and I don't want to see my photo in the future on every letter that was ever written. So, does anyone have a link to a clear see through picture that I can insert so that it doesn't cover up any of the text in outgoing messages saved as a pdf? The extent of my knowledge of photos is point and click the iPhone. Thanks.
