+<h3>External libraries</h3>
+
+<p>Included in this distribution are the most recent versions (as of july
+2006) of the libz, libpng, libjpeg and libtiff libraries. These are not
+required for compilation of libimg, unless you need support for the PNG, JPEG
+or TIFF formats. If your system already has shared libraries for these
+formats, probably it will already work with this package. Otherwise the tools
+are here to build it any time later.</p>
+
+<p>If your system already has later versions than the ones distributed
+together with Img, it is recommended that you always use the latest available
+version. In the case of JPEG no promise is made that future versions of the
+JPEG library keep binary compatiblility, so it might be that you need to
+recompile Img using the latest JPEG header files. If you don't want the
+trouble of recompiling Img, it's problably best to stick with libjpeg 6b.</p>
+
+<p>If you want more information about the external libraries, all of them have
+the latest information readily available on the internet. Img uses unmodified
+versions of those libraries, except that it provides its own set of makefiles.
+The reason for this is that not all libraries supply very good support for
+building them as a shared library. But if you already have them available as a
+shared library, there should be no need to rebuild them. Here is an
+overview.</p>

+
+<p>If you have a problems with any of those libraries, please first try to
+recompile them using the makefiles supplied by Img. If that works, it's an
+indication that something is wrong with the original distribution of the
+libraries, and you better report it to the instance where you got it.</p>
