So this is the old Seek website where most of these images were used. Note the footer at the bottom. I think it's reasonable to assume that any disclaimers would be included in the footer (after all, their copyright notice is).
As I scroll through, the footer remains the same.
However it's only when I reach the really bottom does the "images are simulated" disclaimer appear.
If you have a footer that doesn't move with the page, it's entirely reasonable to assume that all of the disclaimers that normally appear at the bottom of the page are included in it (and the footer shouldn't ever change). You shouldn't have (one of the most important) disclaimers appear in this fixed footer only when the bottom of the page is reached. Additionally, even if someone scrolls to the bottom of the page, they probably won't notice it as it's assumed that the footer doesn't change.
I'm probably getting this thread a bit off topic, but I think it's pretty bad that seek uses these "simulated" images that aren't even remotely close to the real thing. While for people who are vaguely familiar with Thermal imaging it is clear that the pictures are fake / not produced with a $200 device, do note that the Seek is targeted at people who may have never seen / used thermal imagers. In fact, I come across a lot of people who still think you can do thermal imaging by removing the IR Cut filter in front of a CCD - to them a 4 megapixel thermal image coming out of a $250 device doesn't seems impossible at all - after all, some cheap $100 point & shoot could probably do that. And the problem I think is that those people can be easily mislead by Seek's "simulated images" of this kind.
