Right click, view source

That might work if you are right-handed and using a two-button mouse
(and an agent that supports context menus.)

I think it could be easy to do:

the line is a simple div whom position follows the mouse's cursor

css:
====
#demo { position: relative; width: 500px; height: 300px; }
#demo img { width: 100%; height: 100%; }
#line { position: absolute; top: 0; width: 2px; height: 100%;
background: green; display: none; }

JS :
====
function line(evt) {
evt = evt || window.evt;
var x1 = document.getElementById('demo').offsetLeft-1;
var x2 = evt.clientX? evt.clientX : evt.X;
document.getElementById('line').style.left = x2 - x1 +'px';
}

html :
======
<div id="demo">
<img src="asm1.gif" alt=""
onmouseover="document.getElementById('line').style.display='block';"
onmousemove="line(event);"
onmouseout="document.getElementById('line').style.display='';">
<div id="line"></div>
</div>
