What's difference between PS and ImageReady?

Yes, I'm sure you "have" the latest versions. Anyway..

Photoshop is the main tool used for manipulating photos, and doing most of your image editing work.

Imageready is kind of the internet component to photoshop. It allows you to compress images to reduce the file size, create animated GIFs, slice up your images so that you can put them into a web page, and it can even create rollovers for your you navigation bar for you.

That's basically the difference....

Cant PS optimize images for the web just the same?

Yes, but imageready allows you more features like having a four panel display open that shows what your image will look like save as a gif or jpeg, and at different compression levels so you can compare file sizes and image quality to choose the best quality.

I use PS to save single images for the web, but if I need to save a lot of them, or slice up a web site interface into pieces so that I can put it in a table or DIV layer layout, then imageready is invaluable.
