That (lack of padding) is the one drawback of MarsEdit, and was the reason I did not pick it my first time around. If you take a look at most of the posts here, you’ll see that the images are full width, so the padding issue doesn’t come up often. I have been thinking about using a TextExpander snippet with the HTML code for the padding, but for now I copy and paste the code, or move over to Live Writer if I really need to do it. It sure would be nice if MarsEdit would add that.
