urls are stored where?

Hello Everyone
I have fckeditor in a drupal site. I'm posting this here in the hope of finding a solution to a problem I have. Not really an issue because of fckeditor , but comments might give me a greater insight into how this fantastic editor does things . Here is the post I made in the drupal forums -
I recently changed server and at the same time moved the site from a directory to root. I went from example.com/home to example.com . Before I did so I edited the file path and image path etc and then loaded the database.
Everything was and is good . All images are showing in galleries and blocks , everything is pointing to where it should be , except for any images associated with fckeditor . All images loaded into posts using fckeditor (using imce ) , any smileys in posts via fckeditor, are giving me page not found in my logs , and of course the images are not showing in the posts . The urls to all these smileys and images are showing the /home/ directory so if I edit the /home/ out of the url , the image shows.
Posts made since are of course all showing correctly .
Is there any way I can do a search and destroy on the /home/ wherever it is in any links ? Is there some other approach I could try?
Where are these urls recorded ?
That would be good to know
Thanks for any help anyone can offer.

I realise this is a long shot here and perhaps not an issue exactly for these forums , but you never know . I had to come here to read and learn and try and get the font/colour/style/size buttons working so better to ask than not
Thanks for your time
