You can find images through the various internet guides like Excite, Lycos, etc. or search key terms like backgrounds or icons in search engines. Once you find one page, there are usually lots of links to others. Full Tiles is a good place to start. Types of images Backgrounds are pictures, colors and textures that serve as the wallpaper of your page. Be careful to choose light colored, subtle ones so that your text will show up.
Buttons are icons designed to be targets for clicking on to take the user to another page.
Animations are pictures that move. Bars - are images that reach across the page, used to separate sections of text or images. When you have found an image you would like to use, the first step is to save it. I have a folder called images in my personal Y-drive folder where I collect images. Later, when you insert an image into your web page, the software will automatically save a copy of the image file in the same location where your web page is saved.
