My intuition would be that while people may be fooled initially, with that kind of thing it's easier to show that it's manipulated and then people take it less seriously. If you show someone an image you claim to be true and it turns out to be faked via Photoshop, most people don't keep believing it's true. I think the more insidious misinformation is harder to disprove as easily and as directly.
