Can no longer edit/update post : hangs on save

Hi SI team

I have been having problems here:

http://stackideas.com/forums/publishing-post-from-draughts-fails

So I thought that I would do something really crazy.
I started this post all over again and got at least further than the last time:

http://finalbug.net/blog/entry/467-you-tube%C2%B4s-copyright-robot-collateral-damage

FYI I have no idea why the above link is pasted twice.
I pasted it once & only see it once in edit mode!!!

There are still problems:

a) For what ever reason all images are being shown on the main blog page:
http://finalbug.net/blog

The above post

i.e.:

You Tube´s Copyright Robot & Collateral Damage

Should look like the previous post

i.e. "Going Mustang Without a Data Wrangler!"

b) I can no longer edit the blog post to make minor formating changes.

This is a big deal as this is the 2nd time I have run into this problem
I can not create a new post every time the old one breaks and then throw the old one out.
If I continue like this I will still be editing this post until Christmas!!!

c) The last link is broken
Not a big deal. But I wonder is it possible that it broke the save on the post as it was one of the last things I added before things went south!

Please advise

Paul
