+
+## Description
+Proof of concept for send an image over key reflection using two methods of converting bytes to key presses.
+
+## Config
+Un-REM the method to try. And place and image at the C:\Users\{Current user}\test.jpg. 
+The smaller image the better a file of 807 bytes took about 7 mins.
+
+## Props
+To Darren and Korban for all the hard work they have put in to new ducky & key reflection. And for answer my questions i had about the duck before i had it.
+To I am Jakoby for shorting the System.Windows.Forms bit
