What is an image appropriate?
Well, Images that represent you or your product are appropriate. Such as logos or product images. Or perhaps screenshots that help to explain a process.
It is perfectly acceptable to use images as design elements such as bars, bullets, and navigational arrows. But use these with a lot of self-control and only if they compliment your website.
Viewing other websites is a good way to find out what not to do. There are ebooks of all levels. Good ones and bad ones. To decide which is the best way, shop around, be a viewer yourself, and decide as a viewer before you become a designer.
The most important tips is to remember to use images only as they are appropriate. Never for just the sake of using them. They will only promote confusion with in your ebook. Those dancing babies are neat. but probably don't belong on your website. Also drop the annoying flashing gif animations that are hard on the eyes and will be distracting to your visitors.
If you wish to use banners on your website, be careful in your selection and place them at the bottom or top of your site away from your main content.
