Ok I changed the variable to
Its value is ‘gnus-block-private-groups’

Still the math png are displayed. My setting is

(setq gnus-mime-display-multipart-alternative-as-mixed nil) ; most important
(setq gnus-mime-display-multipart-related-as-mixed nil)
(setq gnus-mime-display-multipart-as-mixed nil)  
(setq mm-discouraged-alternatives '("text/html")) ;standard setting for quotes in gmail
(setq mm-text-html-renderer 'shr) 


So am I save with this setting?
