It doesn't validate because it is not allowed in our DTD. See 
http://forrest.apache.org/dtdx/document-v20.dtdx.html#img

The reason it is not allows is because this is layout information and 
should not be part of the source document but part of the CSS describing 
the layout.

To achieve what you want you will have to give your img element a class 
like this:

<img src="../../images/1920.gif" width="155" height="81"
alt="1920s image" class="topAligned"/>

Then in your skinconf.xml file add this class to the extra-css element, 
defining it as you require, for example:

img.topAligned { vertical-align:text-top }
