You need to get rid of the "height: auto" lines, because of the way IE interprets it.
<img width="110" height="auto" class="Right" alt="sample art" src="art_pics/02-Cent.jpg"/>
You should read http://www.w3schools.com/tags/att%5Fimg%5Fheight.asp
The height attribute only has pixels and '%' attributes, so using 'auto' will not work.
pixels The height in pixels (like "100px" or just "100")
percent The height in percent of the containing element (like "20%")
May I suggest using this free HTML validation service. It's not perfect, but it will let you know if there are any glaring erros with your code, in terms of adhering to standards and what not. http://validator.w3.org/
