Container box surrounding images

I'm building a photo gallery and have a problem. The main images have what looks like a dotted container box surrounding them when you click them. This box has padding either side which I want to either reduce to the size of the image or eliminate all together but don't know how to do this. The link is below. Click a thumbnail then click the larger image to see the dotted line. Thanks for any help.

Got it fixed? As i dont see any dotted lines at all.

 

Yep got that fixed although I've now another problem. I wanted to reduce the width of the page to incorporate it into my website. Now the thumbnails are lower than the main image and the text is not aligned to the center. Any ideas please?

 

Have a look at your css containers, most likely just a padding/margin issue

 

Sorry for the late response but it's all fine now. Thanks
