I think I encountered a bug with the image manager for the 2009 Q3 radeditor. It works fine in 2009 Q1.
I am using the RadEditor in DotNetNuke 5.2. When inserting an image, the image has a url which looks like this:
src="/portals%09estt/images/logo.gif" or src="/portalstestt/images/logo.gif. Notice the '%09' in the first case and the missing '/' in the second. This is for a parent portal for a site which looks like testt.example.com. This site has a portal folder called 'testt' under DNN's portals folder.
I did several tests and I think I found a pattern.
The image manager works fine if the url is a domain name like example.com. If the site is for a subdomain like sub1.example.com then the path to the images are broken as mentioned above and the image manager doesn't show any image previews.
When I did the same tests for 2009 Q1 version, everything worked fine. The Q3 version I used was 2009.3.1104.35.
