If you zoom in the .png file, there are some dots at the top and bottom of the picture. It seems that it is a morse code, but I am not sure about this.
This is what I found:
Top dots translates to the word -> "Look"
Bottom dots translates to different things as it is not clear where the beginning and ending of the dots are (the "or" is not part of the translated morse code) ->
I A S A D E or
F 5 B or
I 6 I B or
F S I D A
Maybe there is more to this?
I'm not sure if I found every combination of it, or if its something at all...!?
Have fun
