If you re wondering about the number 7 on the equation, the watermark is inserted every 7 pixels. Why not in every pixel? You could, but this way, you can add a second watermark (and a 3rd, and a 4th, etc.) at the same time using the pixels in between (not scripted here yet). And the insertion process is complete. The new image is saved as a bitmap format (.bmp) which saves the data as it is, without any compression whatsoever.
