There has been lots of stuff you can do to videos for a while, it just takes a lot longer and is likely harder to make something convincing under decent lighting and picture quality for any length of time, but the technology has been moving in leaps and bounds. The quantity of pictures on the other hand, are just a matter of how much time you can afford to spend on each one (assuming you're decent with editing). If you're making any money by lying to people about your dick, you've got that covered.
- On the other hand, as you suspected, the exceptionally large random amateur dick you see online where they only have one or two images are typically going to be bullshit.
