I’ve developed a very simple image viewer extension. It provides a dedicated window in which you can load different images from your local drive. It has no on-screen controls; instead, it works with GP Script, which provides a lot of flexibility with how you incorporate it into your gig file e.g. you can change images using radio buttons, or change images via the Timeline Actions in the Streaming Audio File Player.
The downloads for Windows and MacOS are in the Releases section on GitHub. I’ve added some example scripts for the radio buttons and timeline action examples on the Readme.
