my moms camera is a kodak and about 3 yrs old
she says that when she takes a picture it take like 12-15 sec before she can take another
I've had two Kodak cameras and thought that this was a problem, until I realized that you can get your camera ready to take another pic by lightly pressing on the shutter button. If we're talking about the same thing, the pic that she just took is previewed on the screen for about six seconds (12-15 might be an exaggeration) so she probably thinks that she can't take another pic yet (that's what I used to think).
However, if you're talking about her getting the blue screen that says "processing image" (or something like that) it might be something else. I occasionally get that screen when I take too many pictures in succession without letting the camera process 'em.
