Javascript debugging mystery

I have 2 pretty similar page... the only difference is the images loaded in t开发者_如何学Gohe array... one work perfectly (rotating picture) the other error all the time :

Error: this.img is null
Source File: http://www.fibro.ca/js/blender.js
Line: 54

I check out thing.. copy/paste code and do all i can think of... no luck... do somebody have a divine illumination over that problem... ?

page that work : http://www.fibro.ca/html-ang/25-PIS-fiche.php?numero=1

page that error out : http://www.fibro.ca/html-ang/44-SPA-fiche.php?numero=1

They are not identical "except for the images"

The "page that works" is the one that is throwing the error you mentioned and some some incorrect javascript in it:

$("fichephoto").observe("click", function() {

running = !running;

if(running) { blender.start(); }  
else { blender.stop(); }
});

    new Blender("swapphoto", images, {fadeDuration: 1,displayDuration: 1});

    });

Whats up with the extra Blender at the end? You are not setting it to a variable, so how would you be using it?

Also, it would help if you did some better indentation, makes the code a little easier to read.

You are missing:

new Blender("swapphoto", images, {fadeDuration: 1,displayDuration: 1});
