.NOTES
	This script will convert an approximation of what your image should look like. Most likely you'll need to test several images to find one that works 
	well. It is best to use images no larger than 150x150 pixels, but I would even recommend going smaller than that. My exmaple image is 25x20 pixels	
	To increase the size of the pixels add more spaces to the following Write-Host command.
	Write-Host " " -NoNewline -BackgroundColor $BackGround 

.DESCRIPTION 
	This program will take the path of an image you provide and convert it to a Bitmap file. An algorithm will be used to calculate the closest console color
	that can be used in powershell. Finally that image will be drawn in a powershell window.

	"$env:TMP\omg-ico.png" | PS-Draw
