XnView Software

Hi, can anyone tell me how comments work? I select a file. I hit Ctrl+D. I enter a Description and an embedded comment. After that I upload to Flickr and can see neither of them. Are these not embedded at all? Also, is there no way to hunt for a comment or description? Are they just there for reference if I hit Ctrl+D in the future? There seems to be no way to see them in the Info panel for instance.
Thanks for any help!

Description is only added in a file descript.ion so flickr can't see it.
Comment is embedded in the jpeg, so perhaps Flickr don't support it
