I want to have a solid border around my images (in all posts/pages), but then I want spacing OUTSIDE of that border (just to separate the images from the rest of the post-contents).

I notice that "Padding" adds padding between the border and the image. But I want to add it on the outside of the border. How do I do this?


I tried typing "spacing: 15px", "margin: 15px" etc. but I can't seem to make anything happen.

What's the magic word here???

not exactly what you want, but try this for a frame about the image
at ATO->Style Images->Images in Posts put this in replacing what is there

float: right;
margin: 0 1em 1em 1em;
padding: 15px 15px 20px 15px;
display: inline;
text-align: center;
border-color: #CCC #999 #999 #CCC;
border-width: 1px 2px 2px 1px;
border-style: solid;
