If I want to add short blogs to my stockphoto site,
a) is it best to create a separate wordpress blog site and link it to the Symbio site via an external link or
b) can you use the Posts (or pages?) in the existing Symbio site and incorporate the blog structure (current and archives) in the menu?

I have an existing blogsite at www.advantica.wordpress.com, used for general blogging, but there I don't mix image pages and posts (images are included directly in the posts).

If I want to add blogs directly to the Symbio stockphoto site, should I write blogs as posts or pages, and how can I separate them from the image pages?
 
Thank you in advance,

Les
