+        If you are loading bitmap images and you get an error like
+        <code>"Cannot load image (no suitable loader/converter combination available) for
+        myimage.tif (image/tiff)</code>,
+        you maybe be missing the necessary ImageIO codec to decode the image. A number of
+        well-written codecs can be found in
+        <a href="https://jai-imageio.dev.java.net/">JAI Image I/O Tools Project</a>. Just download
+        the distribution and add the JAR to the classpath. ImageIO will automatically pick up
+        the new codecs and they will subsequently be available to the image framework.
