Trouble with captions and image alignment. Any advice greatly appreciated.

Hi Guys and Girls,
I’m having a lot of difficulty trying to get images within the [caption] tag to align properly. I’ve tinkered with the margin’s but, thus far have had no success, and i’m wondering if someone here can help point me in the right direction. A screengrab of the issue can be viewed here. The captions below the images will vary in length, thus rangin between 1 & 3 lines, however I’d like it so all the images align with each other horizontally in two columns.

I’ve also attempted to change the border colour without any success. Below is where (to the best of my limited knowledge) i need to make the amends to the style sheet, however i’ve had no luck so far.

Any help would be greatly appreciated.

Below is a grab from the style sheet, as it is by default.

/* 2.2 Image Alignment --------------------------------------------------------------------*/
.alignnone {
  margin: 5px 20px 20px 0;
}

.aligncenter, div.aligncenter {
  display: block;
  margin: 5px auto 20px auto;
}

.alignright {
  float: right;
  margin: 5px 0 20px 20px;
}

.alignleft {
  float: left;
  margin: 5px 20px 20px 0;
}

.aligncenter {
  display: block;
  margin: 5px auto 20px auto;
}

a img.alignright {
  float: right;
  margin: 5px 0 20px 20px;
}

a img.alignnone {
  margin: 5px 0 20px 0;
}

a img.alignleft {
  float: left;
  margin: 5px 20px 20px 0;
}

a img.aligncenter {

  margin-left: auto;
  margin-right: auto;
}

/* 2.4 Image Border --------------------------------------------------------------------*/
