Hallo,

Ik kom er niet echt uit nadat ik een leuk script vond op internet om geregistreerden fotos te kunnen laten uploaden.
Het script wat ik op deze site vond resized verkeerd en had een directory overzicht. Echter hebben ze maar toegang tot 1 map.
Vandaar het script wat ik nu heb gevonden, maar... ik probeer al twee dagen de waardes vast te zetten die je nu nog kan invoeren.

Nu krijg je de optie om zelf de rezise in te voeren, maar ik wil dit graag vast hebben naar 400 x ongeveer 300.

Wil iemand mij hierbij helpen a.u.b. ?

 <?php ini_set("memory_limit", "200000000"); // for large images so that we do not get "Allowed memory exhausted"?>

// upload the file

	// file needs to be jpg,gif,bmp,x-png and 4 MB max
