JavaScript Replacing src on image with javascript replacing image in illustrator,replacing image in indesign,replacing image

I'm trying to replace the src of an image and I currently have this: 

if(('product-img img').src = "/webimages/blank.gif") {
   $(".product-img img").attr("src","/images/blank.gif");
}

It is working but it's happening to all the images on the page. I only want it to happen if the image src = /webimages/blank.gif. I've also tried $(this).attr("src","/images/blank.gif"); anyone know what I'm missing? Thanks
