When Umbridge declared herself the new Headmistress, she had Filch take down all the portraits in the schools. That wouldn't really make any sense for the entrance for the Gryffindor common room and the entrance for the kitchens since to get into either one of those rooms you have to do something that involves the painting. Did Filch not take down the Fat Lady or that picture of fruit or did he actually take them down so anybody can easily get into both of those rooms?
