This is a sub panel in a detached garage, which I am not real familiar with. It looks like the ground for this panel comes from the dwelling with the conductors. There is no ground rod outside on the garage. Am I correct that this panel should have its own ground rod, separate from the dwelling. Also there is a ground wire on the neutral bus. I have read this is incorrect on a sub panel. Would it be allowed if this panel has its own ground rod?

Thanks in advance for any insight

The bare EGC should not be on the neutral bar and yes the separate structure requires a GES (grounding electrode system) typically two ground rods. All of the EGC’s twisted together under a single lug is a violation also.
