If you wish you could view thumbnails in explorer like you could with "Pre-CS" versions of Photoshop then CHECK THIS OUT. Personally I think the "Bridge" blows.
I've got CS2 and I can still see all my thumbnail's in explorer just fine.
I don't mind Bridge so much, I just wish it was a little quicker. Although my laptop seems to have been misbehaving and perhaps that's what cause's Bridge to be slow? :S
"To photograph is to hold one's breath, when all faculties converge to capture fleeting reality. It's at that precise moment that mastering an image becomes a great physical and intellectual joy."
