How to Resize JPEG Images to a Specific MB in CS3
Adobe Creative Suite 3 offers a highly integrated system by which to create and manage a wide range of creative projects. Photoshop is one of the more versatile programs in the suite, making it possible to optimize your photos and images for print or web use. Since speed is one of the key considerations in working with digital images, it is important to understand how to manage the file sizes of the images you are working with.
