Flexible image containers

THe following two images are contained within "flexible" containers. They have a min height and min width, but expand when the contained image is larger than that.

/* basic min height/width setup */
div {
			border:1px solid #900; float: left; min-width: 75px; min-height: 75px;
		}
	
/* IE fix */
* html div { width: 75px; height: 75px; }
	
img { vertical-align: bottom; }
