Hi Craig,
Are you displaying the images from two different domains with different paths? eg: /assets/images/cmsb/ is needed on one domain but /x/assets/images/cmsb/ is needed on the other domain?
If so, one solution is to use the same domain for everything, eg: domain.com/x/ to get to the cms.
Or alternatively setting an absolute url on the Upload Folder Url values in the CMS so the appropriate absolute url can always be determined. eg: http://example.com/uploads/
Let me know if either of those options work for you.
