If we use the sharepoint image manager, it only works with IE. - The default asset picker of MOSS is not cross browser. It works only in IE. This is a known issue.
If we use the RadEditor image manger, it can only access the libraries within the current site and I am not able to navigate the site tree to go to the parent site. - Unfortunately the ImageManager provided by Telerik does not have the described functionality. You can control which libraries to be loaded by the ImagesPaths
Here is some additional information on how the ImagesPaths
By default, all the libraries from the current site are included in the ImagePaths collection.
When you set path starting without slash (e.g. "ImagesLibrary"), you will refer a local library - library from the current Web. If you set path staring with slash (e.g. /ImagesLibrary), you will refer a library from the SiteCollection (root).
Lets open the SubSite1 ConfigFile.xml and set the following images path:
The ImageManager will load the SiteCollection/SubSite1
If you set the path with slash the ImageManager will open the SiteCollection
Also you should know that if you set e library such as SiteCollection/SubSite1
/ImagesLibrary, the currently logged user should have at least reading rights for all site collections of the path. Otherwise the ImagesLibrary will not appear in the ImageMangager dialogue.
