Upload, Resize, Rename
Poosje geleden dat ik op het forum heb gezeten, maar bij deze weer ;)
Ik heb van internet een script gedownload waarmee je afbeeldingen kan uploaden en dat hij ze automatisch aanpast qua grootte, fantastisch echt waar! Maar nu zoek ik eigenlijk een functie waarmee ik het geuploade bestand automatisch een andere naam geef.... En eigenlijk dat ie kijkt of 1.jpg, 2.jpg, 3.jpg enz enz al bestaat en dan automatisch een daarop volgend nummer geeft :S lijkt mij last en vraag me af OF het mogelijk en zoja misschien kunnen jullie me dan op weg helpen. Hieronder de code die ik nu gebruik:
