Jimmy Wachtel on Buckingham Nicks credits

[Nikolaj]

Hi, just Googled it and got part of my own question answered, so I'll reword this- In the Buckingham Nicks (gatefold) inside liner notes, Jimmy Wachtel is listed under Album Design and Photography. Lorrie Sullivan is also listed as photographer.
Yet, Waddy Wachtel is only listed in the credits as 'Waddy' and not Waddy Wachtel, so I originally wondered if Jimmy was Waddy's real name, but it's not, it's Robert, which most of you probably know. Kind of odd that Waddy didn't use his last name back in 1973, or was it because 3 Wachtel credits on one Stevie-Lindsey album would be one too many?? (Jimmy Wachtel is listed twice)
So, I think this Jimmy Wachtel is Waddy's (Robert's) brother. I may need to re-edit, I only got as far as Jimmy isn't Waddy and wanted to ask here on The Ledge because I don't recall any talk of Waddy not using his last name professionally, and of Jimmy Wachtel being in the equasion of Stevie's career, but obviously, he was.
So, was it this Jimmy Wachtel who made Stevie take off her blouse for the album cover, or the other photographer credited, Lorrie Sullivan?
I don't seem to recall either of them working as a photographer for Stevie again....
