this is an example of how to read and write infotext when developing an extension for Stable Diffusion web UI.
Infotext aka PNG Info, the purpose of which is to allow an image to be re-creatable by saving the generation parameters in the images itself.
Webui provides an interface to read and write infotext, but its usage is not well documented.
