I made a simple script that automatically changes my community banner and icon based on the latest post.
I mod a small community about digital bioacoustics(using AI to study animal communication/sounds). I made a little tool, it's nothing too extraordinary, but I enjoy it. basically it's just a google cloud function that monitors the community, when it sees a new post it generates an AI image based on the title and sets the banner and icon with it. It also catalogs all the images and leaves them as comments in my main stickied post of resources.
