The Extension:MultimediaViewer have a really nice funciton where it can read the browser window size and provide proper size thumb image, instead of simply give user the huge original image.
This function could save tons of bandwidth cost and let user get the image much faster. It would be AWESOME if FancyBoxThumbs have such thumb support!
Will hug the guy/girl who wrote this function for FancyBoxThumbs 100 times!
