postimage.org is a popular cloud storage unit for forums and blogs etc, unfortunately for reasons unknown their domain was blocked and as a bandaid they had to use the .cc TLD inforder for users to get their images back in business
i use wordpress and it was easy to fix the problem but not sure about forums and crm packages like this one
I am aware that search and replace is crude but whether there is a broken link checker like there is for WP is not known
