I am having some trouble manipulating images using CodeIgniter 1.7. With the following code, the image is uploaded correctly, but, instead of a new image being made and then modified, the existing image is modified. Any help?
//Upload image first
$config['upload_path'] = './uploads/';
$config['allowed_types'] = 'gif|jpg|png|bmp';
$this->load->library('upload', $config);
$this->upload->do_upload();
//Now fix the image
$picloc = $this->upload->data();
$picloc = $picloc['file_name'];
$thumbnail = "thumb_".$picloc;
$imagemanip['image_library'] = 'gd2';
$imagemanip['source_image'] = './uploads/'.$picloc;
$imagemanip['new_img'] = './uploads/'.$thumbnail;
$imagemanip['maintain_ratio'] = TRUE;
$imagemanip['width'] = 250;
$imagemanip['height'] = 250;
$this->load->library('image_lib', $imagemanip);
$this->image_lib->resize();
