Dear George, Steve and Herbert,
Thank you very much for your replies and willing to help. I really really appreciate it!
All the above solutions have made me to better understanding how WordPress Works. Thank you once again.
Herbert you were right, I guess that I was confusing when I wrote about the Demo site and categories.
What I am willing to do is to have on absolutely every page all the categories on the bottom of the page. For about 8000 photographs I need around 20 categories. Now, on the first Demo page there are only 8 categories, so all my 20 might look a little bit cramped but I would still try. Is there a way to do this from Dreamweaver? I have some basic html knowledge but the last time “I went” inside the code of a WordPress was around 2005 – now everything looks to weird 🙂
