Here is a javascript to display the images scripts that are not displayed in a page. I have sceen forums of some sites 
where print view  or printview diesnot display images its just shown as links. this code works with firefox to display 
the pages in printview where the images are not displayed. in thread view there images are genearlly displayed. 

Ideally a script to display images that are not displayed . wordpress or blogs u see the problem . 

// ==UserScript==
// @name           Show Image
// @namespace      Pics
// @include        *
// ==/UserScript==

String.prototype.contains = function (it) { return this.indexOf(it) != -1; };

File = new Object();
File.Exist = function (fileToCheck) {
    var tmp = new Image;
    tmp.src = fileToCheck;
    if (tmp.complete) {
        return true;
    }
    else {
        window.setTimeout('File.Exist(fileToCheck)', 5000);
        return false;
    }
}


var taga = document.getElementsByTagName("a");

var odi = new Array();

for (var i = 0; i <= taga.length="" -="" 1;="" i++)="" {="" if="" ((taga[i]).innerhtml.tostring().contains(".jp"))="" {="" (taga[i]).innerhtml="taga[i].innerHTML" +="">";
        taga[i].removeAttribute("target");
        taga[i].removeAttribute("href");
    }
}



var Images = document.getElementsByTagName('img');
var i = 0;

    imgstring = imgstring.replace(nozerostring, "<--number-->.");
    var i = 0;
    var retval = "";
    var exit1 = 0;
    for (i = 1; i < to;="" i++)="" {="" var="" im=""><--zeros-->", zerostring).replace("<--number-->", i.toString());
        if (i==1 || i == 10 || i == 100) {

                }
            }
        }
        retval = retval + ("");
    }

    
    newwindow = window.open();
    newdocument = newwindow.document;
    newdocument.write(retval);
    newdocument.close();
