Welcome to the Q&A Forum

I've run the seomoz on page report and found an interesting issue. I'm using wordpress and it seems that every picture I add to my articles seem to be added as separate pages to the site. I'm having to go to each and every picture and creating a meta tag and description to it. I still get duplicate content issues with the same. On my Disqus system, I get the same pictures added just as a page or article would look like. What can I do to avoid this?
