About optimization Adobe Photoshop display quality and file size images

Optimization is the process of adjusting the display quality and file size images for use on the Web or other online media. Adobe Photoshop and Adobe ImageReady gives you control the effective range for compressing the image file size while optimizing the quality of online viewing.

There are two methods to optimize the image:
* For basic optimization, Photoshop Save As command lets you save images as GIF, JPEG, PNG, or WBMP file. Depending on the file format, you can specify the image quality, background transparency or matting, color display, and the download method. However, all features of the Web - such as slices, links, animations, and rollovers - that you have added to the file is not preserved.

For more information about using the Save As command to save images as GIF, JPEG, or PNG, see figure Savings.
* For proper optimization, you can use the optimization features in Photoshop or ImageReady optimized to view the image in different file formats and with different file attributes. You can see multiple versions of an image simultaneously and modify optimization settings as you see the pictures to select the best combination of settings for your needs. You can also specify the transparency and matting, select options to control dithering, and resize the image to specific pixel dimensions or a certain percentage of its original size.

When you save the optimized file using the Save for Web (Photoshop) or Save Optimized (ImageReady) command, you can choose to generate an HTML file for the image. This file contains all the information required to display your images in your web browser.

Save for Web (Photoshop) or Save Optimized (ImageReady) command that is specifically designed to provide a set of more powerful and intuitive than the option to save the image file for use on the Web. This includes a fine sensitivity and image file sizes of color palettes that are not available from the Save As command. When creating graphics for Web use, Save for Web / Save Optimized command is recommended.
