How many images are on a website? Do a search for site:www.sitename.com and click on the Images tab. This will then pull up a collection of all the images on a site. You can also combine this with a search term, so a search for site:www.bbc.co.uk blair will pull up a collection of all the images on the BBC site that refer to Blair (Tony or otherwise).
When was a webpage last updated? This depends on how a web page is put together. If it's a straightforward HTML page it's worth trying the following: go to the page you are interested in, and in the address bar, type javascript:alert(document.lastModified) exactly as given. That will then pop up a little dialogue box that tells you when the page was last updated. It's not foolproof but better than nothing.
Is there an easy way to find out how many pages/screens there are on an individual website? Go to a search engine such as Google and do a search for site:www.yoursite.com and you'll see how many pages the search engine has indexed. This won't be entirely accurate since the site author may have hidden pages behind a password or in a database, but it should be a reasonable indication of the size of the site.
