Are you using Google Docs to write your website content and articles?  If not, you may want to consider at the very least building your initial "framework" for your pages, posts, and articles within Google Docs.

Just today within my Google Docs account I noticed that there is now a research tab where you can perform a live Google search, search for images, and search for "quotes" well within your Google docs panel.  I have used this with a recent article and it does improve writing efficiency as you don't need to have multiple screens open to accomplish this task any more.

Here is a screen capture of some of the things you can search:

You will notice that you can even search images based on "usage rights" meaning that you can find images that are royalty free and you can use on your website, articles, blogs, etc. 

I just thought I would bring this to your attention as it is another wonderful addition to Google Docs, which is my preferred writing interface.
