I think the suv photo is telling because if you look carefully, that stepstool is there just to get her to be able to reach the RUNNER of the SUV, not even to step inside the vehicle itself. I think it accurately conveys with the other photos, when they are all taken together, not just one photo that can be taken out of context, that shows a deterioration of her health. It certainly does not contradict the other more glaring photos. It might be more arguable that it does not make as many people question her health, because of what you said, but it doesn’t support her in any way that the other photos we have little question about, are accurate. Doesn’t dispel what we see in the other photos.

The average height for an American woman is 5'4" - so she is two inches TALLER than average.
