You can turn the camera off in 2.4 by opening the project and doing Project->Build Options->Project.
Locate the MPLAB C18 tab in the dialog that pops up and click it. Just click the '_USE_CMU_CAMERA' (or whatever it's called. It's obvious) and hit "Remove." Also make sure hte "Use alternate settings" is unchecked. You'll be warned by the compiler that there's a type mismatch with the printfs, but it doesn't matter.

I think...
