Why wont this class be applied to the image?

Question

I have some js code which generates an image-tag like this:

main_pic_div.innerHTML ="<img src='"+path_big_image+"?"+Math.random();"' class='shadow'>";

But the class wont be applied to it...

Here is what you get when you 'view source' in firefox:

    <img src="ad_images/Bilar/441372870_1.jpg?0.6932381395385144"/>

The class isn't even there, why?

I have tried with all kinds of quotes!

Thanks

Answer 1

I think it should be

main_pic_div.innerHTML ="<img src='"+path_big_image+"?"+Math.random()+"' class='shadow'>";

(You left out the plus sign after Math.random())
