As of now we do not support character or image customization within the app. You can however upload your own images or characters to use for free. Please be advised that we do not support animation for custom imported images beyond the basic panning and rotate movement animation.
In the meantime, we recommend uploading animated gifs that you've created/downloaded outside of Toonly. When added into your project, the gif frames will play together with your scene. Please use gif images that are less than 1MB in size.
