You need to be really careful about using stock images on your website! Simply "borrowing" pics from someone else's site that you like (or from Google Image Search) can get you into serious trouble, particularly if the image is owned by a big stock photo company like Corbis or Getty. At least two geeks on here received demands for hundreds of pounds last year because their web designers had used stock images without paying for a licence. There are also search "bots", e.g. PicScout, which crawl the Web looking for unlicensed images on behalf of companies like Getty and Corbis, PicScout, Getty Images and Goodbye iStockPhoto..! - so it's not a question of hoping that no-one will notice that you've used that image without permission - as it's probably just a matter of time before bots like that will find your site (although there are steps you can take to reduce the risk of that happening, like blocking known IP addresses for PicScout from being able to access your website - which can be done in your server's firewall configuration or - if your website is hosted using the Apache webserver - within an Apache .htaccess file).
