Optimizing Your Images for the Web with Adobe Photoshop
When placing an image on a web page your image should be only as large as it needs to be to display correctly on the page. If your image is too large (800 x 600) and you resize it within the Dreamweaver application by dragging its corners, the file size is not reduced, just the visual size of the image. If you reduce the image size in Photoshop to display the correct size on the web page, you can save file space/size and allow the viewer to view the image much quicker. (For example: An image sized at 800 x 600 could be a 2MB file. If that file is reduced to the size needed on the page, e.g., 360 x 413, the file size can be brought down to 436k. This file is easier for someone to view on a web page through their network connection and saves space on the server.
