Could you please give me some more information.
1. The Image Manager load and load too long. - Does the problem library loads eventually?
2. Do you have the same problem with the Documents or the Pages libraries?
3. Are there a lot of sub-libraries in the PublishingImages library? - If there are, you should know that in the next version of RadEditor for MOSS we will include an optimization in the loading of folders with a lot of sub folders.
5. Do you experience the problem if you remove your custom code?
All the best,
