Javascript Image shrinking for specific users

Question

Hi, I have a javascript function for shrinking images but I dont want the shrinking function to work if an administrator logs in.

Here is part of the code

 function shrinkImages(){
 var i=0, maxWidth;
 //if (/^(?:artistnews|albums|news|exitnews|reviews)$/.test(arg(0))) maxWidth=236;
 if(typeof homepage != 'undefined') maxWidth=530;
 else maxWidth=236;
 var first = getElementsByClassName('first');
 if(first.length>1)
  first = first[0].getElementsByTagName('img');
 var imgs = document.getElementsByTagName('img');
 while(imgs[i]) {
  if(imgs[i].width > maxWidth && imgs[i].name!="shadow") {
   if (has(imgs[i], first) && maxWidth==236) {
    imgs[i].height = Math.round(521 * imgs[i].height / imgs[i].width);
    imgs[i].width = 521;
    i++;
    continue;
   }
   imgs[i].height = Math.round(maxWidth * imgs[i].height / imgs[i].width);
   imgs[i].width = maxWidth;
  }
  i++;
 }
 imgs = null;

Answer 1

Define a Javascript variable called isAdmin and set it to true when an administrator logs in, then stick this at the beginning of that function...

if(isAdmin) return;

Answer 2

switch(userType || undefined) #Small update
{
   case 'admin':
      //Nothing
   break;
   case 'user':
   case undefined: /*user or unknown*/
      var imgs = document.getElementsByTagName('img');
      for(i=0;i<=imgs.lenght;i++)
      {
          if(imgs[i].width > maxWidth && imgs[i].name!="shadow")
          {
              //ETC, You know the rest
          }
      }
   break;
}

then within your html head do

var userType = 'admin'; // or w.e

And if you only define it for admin and dont define it for anyone else they still will get shrunk down
