On photography in galleries

I love 303 Gallery and its program, but given the fact that we've been told not to take photographs in the gallery, I find it funny that founder Lisa Spellman is quoted in The Art Dealers saying,

As a student I had been immediately been touched by the generation of appropriationist art and by the intensity of political discussions centering on the new notions of Postmodernism.

The show in question was Mary Heilman's exhibition in 2005. At the time, there were only work images on the website, and no installation views. How can you write about a Mary Heilman show without talking about how the various works relate to each other in the space?
