Hello mmike,

A Plot specifically cannot be made into an image using any features of NinjaScript. You can use OnRender to draw images. You can find a sample of loading and displaying an image in the following post. Keep in mind that loading many images at a time could take a large toll on performance if that code is not optimized, for example loading an image on ever render pass would degrade performance. The sample shows how to reload the image only when necessary.
