Change resolution

I send
cam.setImageSize(VC0706_320x240);

But the cam remain in the prior resolution 640x480 also if in

Serial.print("Image size: ");
if (imgsize == VC0706_640x480) Serial.println("640x480");
if (imgsize == VC0706_320x240) Serial.println("320x240");
if (imgsize == VC0706_160x120) Serial.println("160x120");

Return me 320x200 but the size remain 640x480.

Start with the cam.setImageSize(VC0706_320x240) call and the Serial.print output shown in the issue, then reproduce the camera's reported resolution. Trace why selecting 320x240 leaves the camera at 640x480; done means the selected setting is applied and the serial output reports the resulting resolution consistently.
