Uploader: *klik*
Nog iets: Als ik zo op uploaden druk zonder een bestand te selecteren geeft hij geen error, terwijl dit er toch instaat:
//reads the name of the file the user submitted for uploading
$image=$_FILES['image']['name'];
//if it is not empty
if ($image)

Graag niet bumpen; twee berichten van jezelf na elkaar binnen 24 uur. Heb je een toevoeging aan je vorige bericht, gebruik dan het 'wijzigen' icoontje.[/modedit]

Windows zeven?
Dat is nieuw voor mij :P

Het voorbeeld werkt volgens mij niet. Ik krijg een bericht over dat de website onder review is door de webhosting waardoor de website niet beschikbaar is.
Dat is nieuw voor mij :P

Oh, dat ligt gewoon aan die gratis kut hosting. Als er te veel data naar zo'n account gaat dan wordt ie tijdelijk 'afgesloten'...

Bij mij werkt ie nu ook weer helemaal niet. :S
Dan los je het op.
