Thanks by the way for referencing Natalie Dee. She seems to get her stuff used a lot without credit. :)
Dude, how many posts do you have on your home page? Trying to give Podz a heart attack? :)
Anyway, you might lose your pictures if you delete your blog over at Blogger. I would just leave it up. You might want to set a schedule on moving them over, say 5 or so a day. It's not always a good idea to be trusting another site with your info as you can never know when it might go down.
I would leave the old blog up and maybe stick in a few "Hey, I've moved" posts to ctahc anyone reading it. Plus it will give you addition inbound links for teh search engines.
Hope this helps,
