"Hello, this is Cable for Expert Village. One thing that you should always remember when exporting your inked frames to be composited, or to be put together with other elements on the computer, is that the images should have this extra layer within them called the alpha channel. It's one of the fourth channels in computer image. There's RGB, and there's this alpha channel. Well, in most ink and paint tools, especially the ones with more bells and whistles, you can go through your settings. When you are saving your files, choose an appropriate file format. One file format that has this extra layer is a TIFF file or a PNG file. And when you choose your "save to" options, look for these formates - PNG's or TIFF's. TIFF's are larger good-looking files with not that much compression, and make sure that you look for an option that lets you keep the transparency or keep the layers, and this will help make sure that you can see through the background and you won't have a big white or black square around your image, so that you can composite your animated element on top of the background."
