How do I turn off automatic padding around images

[MicheleJin88]

When I embed images in CMS articles, they look fine on the preview page, but on the article page the image has padding around it, so that it looks indented from the text. I figured out that it is using the value from StyleVars: Common: Padding. If I set that value to zero, the image has only the margins that I set with my html code. But that also gets rid of padding around sidebars and blocks everywhere. How do I turn this StyleVar off for my images without affecting the rest of the site?

Thanks for your help.
