You can query them and on sets, you can change the images. Note that sets are value types, so getting an image set in Lua will always refer to a copy, not a reference. Images are special, because plugin authors can specify a URL that Chatterino will load if the image is shown. While the plugin can't see the response, it still causes Chatterino to issue a request, so _creating_ images will require the network permission.
