Better image compression

I'm digging all the images especially the large first macro photo when you load a gadget review. But I get the feeling that they could go through more efficient image compression without losing that much in quality. Or use thumbnails instead of scaling full-blown images.

 

You know.... Think about your 1 Mbps customers. It takes 8 seconds to load the page, most of it goes towards the huge image files.. Yeah, yeah. First world problem, but still. What do you guys think?
