Find and replace missing images / links


I am currently migrating an old, huge board (existing since 2003...) to XenForo.
ConvertImageAll is great to keep any existing images before they vanish - however, a lot of them HAVE already vanished.

Is there a way (either included or with an add-on) to find and replace missing images or text (i.e. "Image is no longer available")?

Thanks for your help in advance :)
Thanks for the link.

The description isn't clear whether this also checks the img-Links. I always see url only.
Do you know if it checks that as well?
