No, that isn't sufficient. The minimum size required is 4 MP (mega pixels). The size you mentioned in your post is only 1.7 MP (1,067 X 1,600 = 1,707,200) The 300 pixels per inch are irrelevant for your submissions and are only referring to printing standards. As @Jill_C mentioned, submit your images in the highest resolution possible as it will give more flexibility for buyers.
