Wordpress Themes - WP Forum at BFA - Aligning images with captions

Hi there.

When I add a caption to an image it kicks the image to the right slightly (I am guessing it is adding a border or padding somewhere). If possible I would like my captioned images to line up flush left with my non-captioned images.

In Style images -> Posts I have this code:

Code:

margin-top: 0px !important;; 

margin-bottom: 0px !important;;

I tried putting something similar in Caption style but to no avail. I also tried amending .wp.caption img in the CSS by adding:

Code:

.wp-caption img {

           margin: 0 !important;

           padding: 0 !important;

           border: 0 none !important;

        }

but again, no dice. Any suggestions?

I'd like to have a dotted line below the caption as well if that is possible.

Thanks!
