minium grid size?

How can I set the border to a min size around a picture?  http://www.hollandhydroponicoutlet.com/category/1-lighting.aspx

I always set these to fixed height and overflow: none, so...

Just set the css as follows for sub-category-item...

.sub-category-item
{
/* other stuff here */
height: 200px;
overflow: none;
}

This'll make them all the same size and any big images will just show in the box and get clipped.

HTH.
