For example, to create an animation of an eye blinking, you would place an image of the open eye on one layer, and an image of the eye closed on another layer. 2 Choose File > Save for Web. Note: If your image has multiple layers, you can also open the Save For Web dialog box from the Save As dialog box by choosing CompuServe GIF format and selecting Layers As Frames. 3 Optimize the image in GIF format. 4 Select Animate. 5 Set additional options in the Animation section of the dialog box: Loop Continuously repeats the animation in a web browser. Frame Delay Specifies the number of seconds that each frame is displayed in a web browser. Use a decimal value to specify fractions of a second. For example, use .25 to specify one-quarter of a second. See also "About GIF format" on page 260 "To preview an animation" on page 271 "Understanding layers" on page 81 Using transparency and mattes About transparent and matted web images Transparency makes it possible to create nonrectangular images for the web. Background transparency, supported by the GIF and PNG formats, preserves transparent pixels in the image and allows the background of the web page to show through the transparent areas of your image. (Although the JPEG format does not support transparency, you can specify a matte color to simulate the appearance of transparency in the original image.)
