Oh yes, I forgot about that. Sorry.

This should work only in posts:

.post img {

max-width: 600px;

max-height: 800px;

}

I think the max-dimension doesn’t work in Internet Explorer, not sure how much that bothers you? You can additionally add:

.post {

overflow: auto;

}

so that images larger than your post area will not break the layout but simply have a scrollbar at the bottom to navigate it.
