Something Awful [timg] script fix

postimages.js

// jQuery Max Size
// www.labs.skengdon.com/maxSize
;(function($){$.fn.maxSize=function(options){if(typeof options!=='object'){var options={width:options,height:options}};return this.each(function(){$img=$(this);var F;var FW=0;var FH=0;if(options.width){FW=$img.width()/options.width;F=1;};if(options.height){FH=$img.height()/options.height;F=0;};if(FW&&FH){F=FW/FH;};if((F>=1)&&(FW>=1)){$(this).width(options.width);};if((F<=1)&&(FH>=1)){$(this).height(options.height);};});};})(jQuery);

// fixed TIMG script for Something Awful forums
// depends on JQuery, so make sure it's loaded after jquery-min.js. Should work fine with the version on SA (1.4.2)
