I have white borders to all my images, how do i remove it.?

There are a number of places in the k2.css file where the img border is set. You might want to do a search through that file for img. Line 152 has the listing for div.itemIntroText img for starterss

This is what I found:

in line 156 - div.itemFullText img {padding:2px;margin:4px;background:#fff;border:none;}

change to border none as I have done and the border around your image will go poof! :)
