space to start scanning idk if you should use turbo mode or not... it seems faster on both LOL but you can turn on turbo mode by holding shift and clicking the flag!!! if you decide to put in an image, it MUST fill the entire screen, i.e, if you put in image of an apple, no matter how small it is, it must have some kind of background that fills the entire screen, or else colors could bug a little bit.
