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.
