Since Ivovic took such issue with me posting to a resolved issue (yet didn't even get close to a solution to my problem), I will re-post as a new thread in the hope of a solution without the attitude.

I'm trying to eliminate the border around the Seesmic video comment plug in and despite a couple of hours playing with style sheet I cannot get it to go away.
See what I mean on this post: http://www.astrangeweb.net/2008/05/14/overstock-drops-new-york-affiliates/
I don't seem to have the styles referenced in the above reference post in my template (pSimple by http://www.paggu.com/)
The other important information is that my main content page also has this problem - boxes around linked images so I believe the issue lies with the main style sheet and not the single additional style added by the Seesmic plugin.
Help is greatly appreciated.
