The dnd version of project image is kind of ambiguous about the spellbook rules, but magic casting in general requires intention (hence concentration checks) whereas the projected image is essentially a hologram. It doesn't make sense to me that they can affect the Weave enough to cast magic "of their own volition"-- any spell should be channeled through the caster controlling the image. The concept of an illusory version of a spellbook also don't really make sense in the DnD universe.

Compare this to a Simulacrum which requires enough material (ice, etc) to literally create a material, lifesize copy of the caster. It makes sense that they have their own separate set of spells to cast.
