Código PHP:
if(!($this->error))
{
## LOAD OUR IMAGE WITH CORRECT FUNCTION
$this->type = strtolower(end(explode('.', $filename)));
if ($this->type == 'jpg' || $this->type == 'jpeg')
{
$this->img = @imagecreatefromjpeg($file);
}
else if ($this->type == 'png')
{
$this->img = @imagecreatefrompng($file);
}
else if ($this->type == 'gif')
{
$this->img = @imagecreatefrompng($file);
}
## SET OUR IMAGE VARIABLES
$this->x = imagesx($this->img);
$this->y = imagesy($this->img);
}
