Simply register the plugin with ImageIO:
IIORegistry registry = IIORegistry.getDefaultInstance();
registry.registerServiceProvider(new com.realityinteractive.imageio.tga.TGAImageReaderSpi());
For performance reasons, when using this spi use ImageIO methods that use File as argument not Streams
// do not use
ImageIO.read(new BufferedInputStream(new FileInputStream(path.toFile())));
// use
ImageIO.read(path.toFile());
