Photoshop's Save for Web is probably the most efficient way in existence to save jpegs. Even at the maximum quality, it beats most other apps. And you don't need Image Ready to do it. Just press ctrl-shift-alt-s One useful thing to understand about jpeg compression is how it works. A jpeg reads an image in 'areas'. If 2 or more adjacent pixels in a line have the same value, they will be 'bundled' together, and the jpeg will be rebuilt with X number of pixels in each line all having the same color value. This means that the size of a jpeg is highly dependent on the amount of detail you have in it. If you have huge areas of the same color, it will compress well. If it's a mass of tiny details, it won't. mac
