If a pc hasn't got a graphics card installed and just got onboard graphics, what directx stuff can it run.

That depends totally on the motherboard. Most (all?) new computers with integrated graphics card have basic DirectX/OpenGL support. There are API methods to find out exactly what capabilities the computer has that you run on, and you can also look it up manually.

What can a pc do graphics wise without a card? eg just photos and basic video and not much large animation.

At least DirectX provides a software reference renderer, but that is a SDK feature and won't be available for people with only the runtimes so anyone with the DirectX runtimes will be able to run even the most advanced game using the software renderer. It's of course painfully slow though...

If you want to target old computers with only VGA-type support, the rendering capabilities depend of the RAM and CPU the algorithms etc.

There's also some interesting information over at wikipedia:
