Thumbs creation with Image Library - Problem

#1
[eluser]Soares[/eluser]
Hello guys!

I found myself recently with a problem that I couldn't find a solution. Actually, my code was working and suddenly it has stopped.
Well.. The problem is:

I have an image upload form. After doing the upload (which is working okay) I got to create two thumbs - one with 500px and another with 100px. I don't know what I've changed, but now it just not works for certain images. For example, if I upload and image of 250 KB, the thumbs creation works perfectly. On the other hand, if I upload an image of 2MB, the thumbs are not created (although the upload still works).

What might be causing it?

Here is the thumb creation code:

Code:
/**
*    criarThumbs()
*    Após o upload ter sido efetuado, essa função é responsável por criar os thumbnails (big e mini). Arquivos
*    do tipo .bmp não são suportados.
*
**/
    function criarThumbs($info)
    {
        $this->load->library('image_lib');
        $config['image_library']     = 'gd2';
        $config['source_image']     = $info['full_path'];
        $config['create_thumb']     = TRUE;
        $config['maintain_ratio']     = TRUE;

        // mini_thumb
        $config['new_image']     = $info['file_path'] . '_mini_thumbs/'; // sem dizer o nome do arquivo. É automático.
        $config['width']         = 150;
        $config['height']         = 120;
        $config['quality']         = 100;

        $this->image_lib->initialize($config);
        log_message('debug', '[painel_acoes] Classe inicializada');

        echo "\nCriando mini_thumb: ";
        if ( ! $this->image_lib->resize())
        {
            echo "Erro:".$this->image_lib->display_errors();
        }
        else
        {
            echo "OK";
        }

        $this->image_lib->clear();

        // big_thumb
        $config['new_image']     = $info['file_path'] . '/_big_thumbs/';
        
        $width = 600;
        $height = 500;
        $config['width']           = $width;
        $config['height']          = $height;
        $config['quality']         = 100;
        
        $this->image_lib->initialize($config); // inicia novamente, com as novas configurações do big_thumb.
        echo "\nCriando big_thumb: ";
        if ( ! $this->image_lib->resize())
        {
            echo "Erro:".$this->image_lib->display_errors();
        }
        else
        {
            echo "OK";
        }
    }


The variable $info is an array containing the following information:
Code:
Array
(
    [file_name]    => mypic.jpg
    [file_type]    => image/jpeg
    [file_path]    => /path/to/your/upload/
    [full_path]    => /path/to/your/upload/jpg.jpg
    [raw_name]     => mypic
    [orig_name]    => mypic.jpg
    [file_ext]     => .jpg
    [file_size]    => 22.2
    [is_image]     => 1
    [image_width]  => 800
    [image_height] => 600
    [image_type]   => jpeg
    [image_size_str] => width="800" height="200"
)

Anybody has a tip of what might be happening?

Thanks in advance!
