PowerShell "A generic error occurred in GDI+." - powershell

Question

Hi Guys, I'm trying to modify this PowerShell script and put it in windows startup. So every restart a VBScript will call this PowerShell script and it will update the info like a Windows Sysinternals BGinfo.

$image.Dispose();
# Save and close Bitmap
$background.Save($out, [system.drawing.imaging.imageformat]::Png);
