Redimensionar imagens depois do Upload

[m3io]

boas malta arranjei este pequeno codigo para fazer upload e redimensionar um thumb em 150*200,

mas o problema é que preciso tambem de redimensionar a imagem original para 800*600 e não sei como fazer isso,

(mudei tb o codigo pra meter o endereco na base dados mas isso ta tudo funcionando, so falta mesmo a original para 800*600 ou algo do genero)

já tentei duplicar o codigo e mudar as variaveis mas não ta funcionando,

alguém me pode botar uma maozinha ai ???

valeu
