Thanks to all the people who have helped me recently.
By way of thanks I would like to share this little tidbit...
I'm sure, like me, there are those who hate the ugly border that Firefox displays around pictures that are links. Put this line into your CSS and Firefox will behave itself. :focus { -moz-outline-style: none; }
Keep in mind that the dotted-line rectangle is Gecko's way of showing keyboard focus too, so turning it off like that may have accessibility functions.
