If you are using a PoliteMail template and images are not scaling while the text and table are, you can use the mo_re100% fix that allows the images to scale with text and table.

To fix, add “mo_re100%” (without quotes) to the alt text of the image. Right click the image and click format picture (screen shot from Outlook 2013).

Mo_re100 Image

This instructs PoliteMail to change the image height to “auto” and the width to “100%” during sending (something you can’t do in Outlook). The effect is that the images will scale with the table they are inserted in.
