Ik maak gebruik van een script die afbeeldingen upload en resized...
Helaas loopt dit ergens vast.. , ik krijg deze foutmelding:

Warning: Unable to open none in c:/program files/apache group/apache/htdocs/test/upload/script.php on line 116

Warning: Unlink failed (No such file or directory) in c:/program files/apache group/apache/htdocs/test/upload/script.php on line 165

Nu heb ik eerst naar de rechten van de map gekeken.. deze heb ik op alle rechten gezet !!! met windows.. of moet je Apache ook goed configureren daarvoor.

Het controleren van de extensie etc. gaat wel goed.. als je een ander bestand upload krijg je keurig de melding dat het een jpg moet zijn...

Dit is mijn script wat wordt gebruikt:

    SCRIPT CHANGE LOG:

    2002-06-10:

        * Plugged security hole with is_uploaded_file() function. Thanks much 
          to Timothy Rieder for pointing this out.


    2001-01-10:

        * Added line of text letting user know what extension was read in
          when denying a file upload. Suggestion by Sandro Juergensen.


    2001-01-09: 

        * Removed GIF support from script to not encourage the use of
          silly patents. For more info: http://www.gnu.org/philosophy/gif.html

        * Cleaned up the code and comments

        * Moved the extension check out of the size check loop. 
          Thanks Sandro Juergensen <forgetit@sandlatscher.de>

        * Added lower casing the extension check
          
        * Added converting spaces in filename to underscores

    2000-05-31:
        
        * original script released

volgensmij is het script wel goed... maar toch gaat het bij het opslaan of zo fout ?

PHP FAQ: Mijn get/post form doet het niet meer
PHP FAQ: Mijn file-upload script werkt niet

Kijk daar eens naar. En als je geen zin hebt om het zelf uit te zoeken, dan moet je maar gewoon even de maker van het script vragen het voor je op te lossen. We doen hier niet gewoon allemaal onze code posten en maar hopen dat iemand anders het voor ons fixt, sorry.

edit:
foute linkjes fixed
