Implementé el uploader de Snd234, tomandolo desde aquí:
http://www.forosdelweb.com/f18/redim...ad-php-654167/
La cuestion es que me deja las fotos de 750x750. Es decir, no me redimensiona respetando las proporciones. Que puede ser? Yo veo en el ejemplo que hay que pasarle un solo parámetro.
Pongo mi implementación:
Código PHP:
