Where to find Apple product images
Apple Press Info contains a bunch of pictures you can probably use. Depending on the nature of your website you want to clarify copyright issues with Apple before. The Apple trademark page is a good place to start and contains wording that you cannot use Apple images without express written permission, but the contact information is also provided in this link to ask for that permission. As long as you are an Apple developer, you can use photographs of Apple's products with a few restrictions, so that might be a good place to start.
