namad a lot of links don't work not because the install went badly but because all the links to content have changed. SMF used a different URL system than the platform new Curvage is using.
Also images that were hotlinked from the web and embedded using BBcode appear broken because the new site doesn't use BBcode.
In the future this will never happen again because not hotlinked images are automatically downloaded to our server and stored locally.
hope that helps
