The band had basically drifted apart during the Illusions tour. Getting Axl to show up for a soundcheck or rehearsal was next to impossible so he was never gonna show up to a photoshoot with a band nobody seemingly wanted to be a part of anymore.  Then post break up there was, in my opinion a very conscious effort to maintain the illusion that all the various incarnations of GnR were in fact THE classic GnR. So any marketing via band photoshoots that didn't show Slash and Duff weren't how they wanted to market and promote the band. Throughout the entire CD saga there was next to nothing in terms of promoting GnR as a new band, while remnants of the old band were constantly featured heavily in any and all marketing. A full band photoshoot post 1991 didn't serve a purpose. At least not a purpose Axl and Co. wanted.
