That sounds like you're changing the display size without resizing 
the source graphic. That is, you have, say, a 400x600 graphic and 
you're setting it's height and width settings in the image link to 
something less than that. The browser will resize on the fly to the 
size you give, but no browser that I know of has as good an on-the-
fly resizing algorithm as even the cheapest graphics program, which 
resamples the image to resize it.

If this is what you're doing, you're reducing display quality while 
getting no benefit from having your users download a smaller file. 
You need to resize the source graphic in a graphics program, and one 
that is able to resample well.
