[vrijwillig] meerdere images uploaden en een auto thumb maken

Dit is dus een vacature, en voldoet dus niet aan de eisen en staat verkeerd
Inderdaad, zoals gerhard al zei, staat dit topic in de verkeerde categorie. (Ik heb hem nu voor je verplaatst)
Wil je wel even je start post aanpassen aan de hand van de volgende criteria? klik Anders moet ik helaas dit topic sluiten.
Alvast bedankt!

en ben je waarschjnlijk van meerdere te verwachten problemen af.
Niels, dit is helemaal geen vacature! Maak eens onderscheid in "ik zoek een script" en "ik heb een programeur nodig"
Mischien dat er een forum moet komen met "Zoek script / Script Request" welke belange loos door de gebruikers kunnen worden afgehandeld.
