Optimizing a JPEG Document
ImageReady comes complete with everything you will need to properly compress any JPEG Document. The Internet is typically a slow device, and your visitors typically do not have much patience. When you compress a JPEG image, you're essentially removing information from the image to reduce its file size. The unfortunate results of that reduction is loss of image quality. Internet graphics are not always the best for quality; however, reducing file size is a necessary evil, to keep visitors from clicking off your site, and moving to another. To keep the visitors happy, your JPEG images must load fast, and ImageReady is just the application to help you accomplish that goal.
Optimize a JPEG Document
Open a document in ImageReady by first opening the image in Photoshop and then click the Jump To ImageReady button.
Click the Original, Optimized, 2-Up , or 4-Up palettes to view the document using different layouts.
Click one of the sample images to change its default format.
Select the Optimize palette.
Click the Format list arrow, and then click JPEG .
Click the Quality arrow (if necessary), and then select from the following options:
Quality.
Click the list arrow, and then select a preset JPEG quality from Low (poor quality) to Maximum (best quality).
Amount.
Enter a JPEG quality compression value (0 to 100). The lower the value, the more information (color) is sacrificed for image size.
Blur.
JPEG images compress better when the image has soft edges. Apply the Blur option to increase the softness of the image (at a sacrifice to image quality).
Click the Transparency arrow (if necessary), click the Matte list arrow, and then select from the available options.JPEG images do not support transparency. If you image contains transparent areas, use the Matte option to fill them in using a specific color.
Click the Options arrow (if necessary), and then select from the following options:
Progressive.
Select the check box to load a JPEG in three progressive scans. Not supported by all browsers.
Optimized.
Select the check box to further compress the image. Not supported by all browsers.
Preserve ICC Profile.
Select the check box to embed an ICC color profile into the JPEG image. This increases file size but helps maintain color consistency between monitors, and operating systems.
Add Metadata.
Select the check box to embed recoverable data about the files colors, creation, and even author information. Click Settings to specify the data you want.
Click the File menu, and then click Save Optimized to save the current image.
