[SOLVED] Lose gap between images in the sidebar
 

I'm trying to get a column of images to look like one image. The one image is split into 4 and the 4 new images link to different places.

I'm just using href img src etc in a text box to put the images in but there is a gap of about 3 pixels between the bottom of one and the top of the next.

I've looked in style images and that seems to be for posts only, I've looked in widgets but can't see anything relevant.

Any ideas appreciated!

ignore me, I am a fool, it was just the gap between </a> and the next open <a>
