Domain change by postimg

Postimages has moved its files from postimg.org to postimg.cc - so the images all exist under the new domain name, but postimg.org has disappeared without notice. It brings up dead links, including in hundreds of ILX threads. Is there an easy way to update the links to postimg.cc?

This affects "postimg", but links to postimage.org seem to be OK - they redirect to the new domain.
