! 9: * Rename the file to test.php and read the instructions. If the
! 10: * script cannot be executed or does not generate any output check
! 11: * you error log. In most cases this would mean you found an error
! 12: * if the rest of your php environment works fine.
! 13: *
! 14: * The original version of module exif has many errors and mostly
! 15: * fails on executing this script.

! 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.
