CSS.MaxImgLength
TYPE: string/null
DEFAULT: '1200px'
VERSION: 3.1.1
--DESCRIPTION--
<p>
 This parameter sets the maximum allowed length on <code>img</code> tags,
 effectively the <code>width</code> and <code>height</code> properties.
 Only absolute units of measurement (in, pt, pc, mm, cm) and pixels (px) are allowed. This is
 in place to prevent imagecrash attacks, disable with null at your own risk.
 This directive is similar to %HTML.MaxImgLength, and both should be
 concurrently edited, although there are
 subtle differences in the input format (the CSS max is a number with
 a unit).
