Save new image in ignition image management by python

[PGriffith]

How to save the uploaded file in default image folder (/system/images/)?

This won’t work the way you’re expecting it to. The /system/images/ route handler isn’t attached to an actual folder in the gateway install directory - it’s handled entirely in code, and retrieves images from the internal database. If you want to manually upload images, you’ll need to get a reference to the ImageManager on the gateway and call insertImage manually, filling in all the appropriate fields: com.inductiveautomation.ignition.gateway.images.ImageManager#insertImage. Actually doing so …

ImageManager is the way to go, but it's going to be complicated.
