My Blog is Under Attack

Help! I just checked my blog today to find that none of my photos are showing up anymore. When I try to go into WP and see what’s up, I keep getting error messages and I cannot post.

Please see my blog that should be FULL of photos:

http://www.ericsonphoto.com/blog/

I see that if I just add the “www.” to the URL’s, I can get into WP. I still cannot edit though. (The photos will not show up, but I can add a “www.” to their URLs and they show up.}

As this is a site for my business, I am very concerned with this!

Any help is appreciated!
