Hi all, thanks for your help with a couple of SEO questions.

1) Would Google see pages within a subdomain any differently than pages within the full domain?

If I create pages within a subdomain, does Google see them as pages on my site? If I link to pages within a subdomain, does Google see this as links to my site? Do subdomains matter in regards to search engine rankings?

2) Is there any SEO difference between a text link, and an image link with the same link text in the alt tag?

Your opinions on these matters are appreciated, thanks.
