I have a mark on all of my photos using my canon Eos 40D. Is there any one that can give me an idea on what I should look at.

Does the mark appear in the same place on every image? If yes, you might want to try what zdbc13 suggested. Do you see the mark regardless of how you view it (LCD screen, computer monitor, printed)?
 


I'm thinking hotspots (blown pixel or two) on the sensor.
But until we see an actual sample....
 


You're right, hard to really tell without seeing a sample image.
 


 
It's a DSLR, there could also be something on the sensor.
I don't know much on the subject, i know you can clean it yourself if you're careful, and i bet you shouldn't try it until you're sure that's the problem.
The little i know comes from here, about halfway down the page:
