doesn't seem to work (no output picture)

[jbdu94]

Hello

I tried to run this on a mac but it doesn't embed the script and I don't have an output PNG.
Nota Bene: my input picture is bigger than the script I try to embed it to. (3mb for the JPG and 2.2mb for the script to embed).

here are the commands I ran:

Import-Module .\Invoke-PSImage.ps1 
Invoke-PSImage -Script ./Invoke-Mimikatz.ps1 -Out output.jpg -Image ./input.jpg      

New-Object: /Users/mac/Documents/Invoke-PSImage/Invoke-PSImage.ps1:95
Line |
95 | $img = New-Object System.Drawing.Bitmap($Image)
| ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
| Exception calling ".ctor" with "1" argument(s): "The type initializer for 'Gdip' threw an exception."

So I did like that:

Import-Module .\Invoke-PSImage.ps1 
./Invoke-PSImage.ps1 -Script ./Invoke-Mimikatz.ps1 -Out output.jpg -Image ./input.jpg

But I don't obtain an output file. I tried JPG and PNG for the output file,
.\Invoke-PSImage.ps1 -Script .\Invoke-Mimikatz.ps1 -Out out.jpg -Image .\input.jpg

if it may help, I run powershell from a Mac.
Could you please assist me?
