Another annoying thing that comes from factory on the default theme. Ok that’s a CMS looking forward for writing. And does it nice.
But hell! at least it should come with an auto adjust for the images on posts (items) to adapt to the content body.
Fortunately the solution is easy, just adding this lines to the default_right.css that can be found on the skins/default directory (if you are using this layout of course, if not, your CSS file should be over there…).
Max-width defines maximun width for images inside .contentbody, and height: auto keeps the original proportions from the image.
I’ve lost track from the changes that made… anyway, love this CMS.
