Return png. file from a Jenkins Build
I imagine this to be possible in the following way:

Enable (safe) HTML for Jenkins Build descriptions
Enter some html that performs a GET request to a path (let's call this X)
Set up a mini (Python, Flask?) server that serves this path X, and returns the png image from the correct workspace
I have a Jenkins job that executes a python script. I would like to return a png of a figure so that I can see it in the Jenkins Build information. Is this possible?
