Currently the Image cmdlet does not work on Linux/MAC operating systems since Microsoft removed support for System.Drawing.Common on these platforms.
To solve this problem, the SixLabors.ImageSharp library can be used which is compatible with multiple platforms.
I have created a basic implementation to replace the use of System.Drawing.Common with ImageSharp in the following repository rebelinux/PScribo. I performed tests on all 3 operating systems (Windows, Linux and Mac) and the image handling functionality works correctly.
I'm writing to know your opinion about this solution and if you consider it viable to implement it in the current project.
