I have broken link problems :o( and I need some help.?

I created a blog at Blogger, and decided to purchase a domain (simplydelightfulcakes.org) and for a month there were no problems. Then, I was clicking around in Google images and discovered that my pictures were not redirecting to my blog. Instead I was getting the 404 error. So, I used Xenu, and found out (it seems to me b/c I am not a computer whiz) that some one using Twitter tried to share my photos and messed everything up. In Xenu, it also, shows a 401 error (authorization). Then, to make things even more complicated I decided to pay for another domain name (simplydelightfulcakes.net from GoDaddy through Blogger) thinking it would just redirect everything, but needless to say my pictures that appear in Google images still do not redirect to my blog. How do I fix the 401 and 404 error and the broken link problem? Thanks
