+<p>This function initializes the thumbnail system. It must be called
+before any other functions from libgimpthumb are used. You may call
+it more than once if you want to change the <em class="parameter"><code>thumb_basedir</code></em>
+ but if
+you do that, you should make sure that no thread is still using the
+library. Apart from this function, libgimpthumb is multi-thread
+safe.</p>
+<p>The <em class="parameter"><code>creator</code></em>
+ string must be 7bit ASCII and should contain the name
+of the software that creates the thumbnails. It is used to handle
+thumbnail creation failures. See the spec for more details.</p>
+<p>Usually you will pass <code class="literal">NULL</code> for <em class="parameter"><code>thumb_basedir</code></em>
+. Thumbnails will
+then be stored in the user's personal thumbnail directory as
+defined in the spec. If you wish to use libgimpthumb to store
+application-specific thumbnails, you can specify a different base
+directory here.</p>
