183: Images taken from <a href="http://www.exif.org">www.exif.org</a>,
184: <a href="http://marcus-boerger.de">marcus-boerger.de</a>
185: all rights reserved by their authors and artists, see exif headers.
186: The files can be downloaded <a href="http://marcus-boerger.de/php/ext/exif/test/">here</a>.
187: To start the test you simple have to put all images into the same directory as this script.
188: The test will work with all files in that directory and all subdirectories. To test private
189: images just put them into that directory.
190: </p>
191: <p>
192: Youmay take a look at the test <a href="http://marcus-boerger.de/php/ext/exif/test.txt">source here</a>.
193: </p>
194: <p>
195: This test just prooves that some exif headers can be scanned.
196: If all files produce a header in output the module might be o.k.
