Best practice is to insert any links, including images with dynamic path:
<cms:show k_site_link />path/to/resource.jpg
For templates and pages it is
<cms:link masterpage='template'php' />
If you do necessary changes in code, it will be also good for future, when you enable pretty-urls.
Couch will serve proper links in that case.
If your broken images are saved in richtext editor - that is a problem. I don't know another way than manually redo them. Maybe someone knows.
