// NewImageFromFile loads the file with path and returns ebiten.Image and image.Image.
//
// Image decoders must be imported when using NewImageFromFile. For example,
// if you want to load a PNG image, you'd need to add `_ "image/png"` to the import section.
//
// How to solve path depends on your environment. This varies on your desktop or web browser.
// Note that this doesn't work on mobiles.
//
// For productions, instead of using NewImageFromFile, it is safer to embed your resources, e.g., with github.com/rakyll/statik .
