> import org.apache.commons.imaging.ImageInfo;
> import org.apache.commons.imaging.ImageReadException;
> import org.apache.commons.imaging.Imaging;
> import org.apache.commons.io.FileUtils;

> String fileName = "FallHarvestKitKat_07610.jpg";
> ClassLoader classLoader = ClassLoader.getSystemClassLoader();
> File file = new File(classLoader.getResource(fileName).getFile());
> byte[] fileContent = FileUtils.readFileToByteArray(file);

> byte[] decodedValue = Base64.getDecoder().decode(encodedString);
> ImageInfo imageInfo = Imaging.getImageInfo(decodedValue);
