png in generateTreeImage function not working.

[Alex-Wenner-FHR]

I am getting an error when calling the function generateTreeImage and passing the respective parameters. The error I am getting is "FileNotFoundError: [WinError 2] The system cannot find the file specified". I checked the directory and it wasn't there just as the error indicated. I have also went in and tried to create the png file manually in the directory but had no luck there either. Not sure that was the right approach just seemed to be at a loss for debugging this error. Please help resolve this issue! Thanks
