Discuss how you can build links for your website(s). This is not for link exchange requests.
When the pages are linked, the search engines can easily understand them and consequently this in turn can help them to crawl at the site. It also makes it easy for the search engines to work on different internal pages. However, when there is an image in your content, you should ensure that the text links are placed at the footer. It can also be placed in the content or in both the places. It is these text links that would help you to tell the spiders about the specific pages. With footers, you would be able to add more instances.
