This plugin makes it easier for you (or your artists) to use free software, such as Krita, for drawing/editing multi-layer images. It also supports OpenRaster, a standard interchange format used by multiple image editors, most of them free.

For animated files, you can make it use Krita to generate images for each frame and even group those under the same folder.
If you prefer to import textures and sprites directly as sub-assets, you also have a few options using the Import Image method, which never requires Krita.

For example, you can make it so every source image under:
