There are really 2 reasons why you would never want the HTML engine
to do your scaling. First, as has been stated, you have do download the
whole image anyway. Second: Scaling w/o touchup can render some blurry/fuzzy
and generally horrible images. On my site I have always scaled the original
image down to my thumbnail size then applied some type of image sharpening
(in my case, Unsharp mask in Photoshop, but I sure there is an equvalent
operation in most graphics packages).
Another reason to do seperate thumbnails is what Jakob Neilson calls Relavence
enhanced image reduction (and what I call resizing + cropping). see:

So, as always, the method that requires the most work is the best
