Unfortunately, Browser-scaled images look horrible.
My example is restricted to starting with a low quality small image and making it bigger. Clearly starting with a larger higher quality image and scaling it smaller would look neater. For the most part we are talking about scaling of just a few pixels, this shouldn't make much distortion to the image.
Please do try it out. When I tried something similar, it looked horrible whatever I tried, even when starting from a big image. For some reason, only Safari (the Apple Mac browser) does the scaling correctly.
