Drawings scripts and pngs, blank. - (Moved)

[-Mary-]

I've downloaded 2 drawing scripts from here, weirdly it works with some pngs and with others it's just blank, I tried to change the sensitivity but didn't work, or it's blank or completely dark. Someone could explain me why this is happening, I'm not the best with this programming stuffs. 

And if you can, be nice.

So you though we would be able to help you with this? 
Why as you haven't shown anything concrete?
