JavaScript: Preloading Images Preloading images is a technique often used in Rollover Effects or other image scripts which work more quickly when the images for them are loaded as soon as possible.
Multiple Image Animation A script that allows you to display what appears to be a single image animation using 5 different images. The images in the animation will need to be all the same size. The animation repeats indefinitely.
Image/Text Slide Show This script will allow you to display an image slide show from a set of 5 images, with a description below each image. The script shows a new image every 8 seconds, and ends by displaying the first image with the caption "The End".
Image/Text Slide Show 2 This script will allow you to display an image slide show from a set of 5 images, with a description below each image. The script shows a new image every 8 seconds, and then keeps repeating the show.
Image Rollover
This script will create linked images which will change when the mouse passes over them. The script is set up for two image flips, but more can be added by editing the code.
Image Change: Button Click
This script lets you display one image, but have it change 4 more times by having the viewer click a button. Can be used as a user controlled slide show, or just to change an image with a button.
Random Banner Display
This script will allow you to display a random banner from a set of 5. Each banner will be linked to a url of your choice, so this can be used for a random banner ad rotation. You have some display options such as border size, centering, and the banner si
Random Image Display
This script will allow you to display a random image from a set of 5. You have some display options such as border size, centering, and the image size (All images in the set must be the same size, though).
Easy Image Tricks
Have you ever wanted to have an image change to another image when you move your mouse pointer over it, and change back once you move your mouse pointer off it? This can be accomplished rather easily with JavaScript.
A slide show with JavaScript
Have a click-around with the previous and next buttons in the slide show below and see what happens. Then click the check box and wait to see what happens then.
A new image every time you visit the page
Try reloading this page and see what happens to the image below. The more images you have in your ARRAY the more likely a different image will load…
Menu with Descriptions, using images
While this example talks about descriptions for the items in a menu, it is equally about loading images and changing images in a page. For example, when an item is selected in the menu, an image (showing a description of the item) appears on the right of
Image Rollover Script
This script makes an image change when the mouse is placed over the image.
Slide Show Script
This script allows you to display a "Slide Show" where the surfer can change the images on a page automatically.
Random Image Script
This script displays a random image. Instead of getting the time and displaying an image based on that, it truly is a mathematical random script.
Fading Image Script
This script makes an image fade in and fade out when the mouse is over it. It is similar to a regular rollover, but it only requires one image.
Preloading images
JavaScript animation works by substituting one image with another. The new image should be ready to replace the original image as quickly as possible. For this to happen the image must already be loaded into the computer's memory (also known as cache). If
Image Flip Using OnMouseOver
This example introduces you to advanced uses of onMouseOver and onMouseOut events. Remember that with object-oriented or object-based programming, an event triggers a function or JavaScript statement to run.
Producing Random Statements and Images
Before we go on to a new topic, let's look at one more example of IF. It's important to feel very comfortable with this branching technique which lets you create more creative and more interactive programs.

Animated Buttons: THE TECHNIQUE

Image Cycler
Cycle through a group of images in a single location on your page. For best results all images should be near each other in size. You set the time interval for the change of images.

Preload Images
Ever wanted to get rid of the delay that happens when users put their cursor on a image while the 'onmouseover' image loads? Use JavaScript to preload your 'onmouseover' images and the delay is gone! Useful!
Random Click Image
Displays a random image when the page is loaded and each time the image is clicked.
Random Image
Use this script to randomly display a different image each time the page is visited. Refresh this page and notice the image below will change. Any number of images can be used, and set-up is very easy.

Random Image Rotator
Rotates a series of images on the page every few seconds. The images can easily be changed, and the script can be modified to rotate the images randomly or in order.
Rotating Banner
This script randomly displays images, links, or text every time the page is reloaded. (Because it is random, it may reload the same image, link, or text.)
Set Image
Set an image on the page when the cursor is over the link. The image remains set until the user puts their cursor on another link (i.e. no onMouseOut command). Then, the image is updated to the new one.
Textarea with BG Image
Need a quick, easy way to add an image to the background of a textarea? This script is a great way to dress up the bland textareas on your page. Add any image you choose.
Image Swapping

Image Rollovers
An image rollover is basically two different images. One is displayed after the page loaded up, the other one is displayed only when the user moves his mouse over the first one.
Changing Images on Mouseover Using JavaScript
The onmouseover event handler is used for generating various kinds of interactivity on web pages. It's most often used for image rollovers. Image change on mouse over is actually quite simple once we understand the logic…
Image Change Using Functions
The main use of function is to prevent us from writing the same code again and again because we can call the same function with a different set of parameters.
Moving an image
The script animates the image by moving it from its initial location to the specified location.
Blending images
Blending one image into another produces an efficient transition effect.
The Image-object
