Figure 9-7: High-quality and low-quality JPEG fi les on a Web page.
As you can see, the lowest-quality image (let ) and highest-quality image (right) are very
similar. In the context of other materials on a Web page, some quality dif erences may appear.
However, images that have the characteristics of those two shown in Figure 9-7 don't suf er
much in appearance on the Web when i le size is reduced.
A bigger dif erence with JPEG i les sizes can be seen with digital photos. In Figure 9-8, the
photo on the let is the lowest quality (8K) and the one on the right (115K) is the highest, with
corresponding i le sizes.
