Optimization is a process which can be lengthy for perfect results or fairly brief for almost perfect results. You have to weigh in on which route you need to go. Adobe Photoshop and Adobe ImageReady both offer full tool sets for optimizing the file for online display quality. I would use the one I'm most familiar with and the one that's used most frequently. For a skilled user, ImageReady is really not necessary.
The easy way:
Use the Photoshop Save As command lets you save an image as a GIF, JPEG, or PNG file. Depending on the file format, you can specify image quality, background transparency or matting, color display, and downloading method. The controls for the resulting dialog boxes are fairly clear. I recommend saving this way (using a different name) and saving the next way as a means of comparing the two results. Then you'll know for sure which is most advantageous.
I use the "Save for Web" command for greater control and more precise optimization. It's found in the File menu just below the "Save As..." item.
The "Save for Web" window offers a variety of choices. Again, the options here are all fairly self explanatory.
Click on the tab at the top of the image area to choose a display option: I recommend 2-Up so you can see both versions of the image side by side.
The annotation area below each image in the Save for Web dialog box gives you the bottom line info on how the file will perform online. You'll see the original image filename and file size; and the optimized image optimization options, the size of the optimized file, and the estimated download time using a selected modem speed. I recommend using the 28.8 setting to be sure.
Now change your "quality" options to the right, and test various settings.
Nothing will actually change or affect the file until you select "Save Optimized" -- so play around until you have a good visual understanding of what to expect.
You can also set scaling at this time, and Photoshop does a pretty good job of sampling your image down to the correct size. Remember: never enlarge.
