Where can I find a good picture of the Sistine Chapel ceiling?

Wikipedia has photos of it at a decent resolution.
Here‘s the left half of the ceiling, and here‘s the right half.
Does that help?

This website here has very good pictures also.

Life Magazine put out a coffee table book my mother had. it had a beautiful two page spread of it.

@Fyrius That is looking good so far thanks, but I can’t tell just yet because my internet is so bloody slow tonight.

@Bluefreedom Also a great link, thanks!

Look at this to see what you want. It is a virtual model of the whole space, and it is AWESOME, [Do note the copyright medallion in the exact middle of the floor]. Then you could try contacting the Vatican gift shops to see if you can buy a high res digital file to print out whatever size you want

@anartist That is wonderful, thank you!
