instead of using the V4L2 device node to access the stored images, it probably makes more sense to use a separate device for that, that will handle a separate set of ioctl's, and just use read() to retrieve the image data, after selecting the desired image number, via ioctl().
I don't see a lot of added value in doing things this way. We can simply have a set of new ioctls on the /dev/video# node for this and a new V4L2_CAP_STILL_IMAGE to indicate the availability of these ioctls. This will keep the driver a lot simpler then doing 2 separate device nodes for 1 device.
