Intergration between gallery2 and droupal 4.5.x - error

I'm trying to integrate gallery2 and drupal 4.5.x on my site www.web4cu.com/dblog
I installed gallery2 in www.web4cu.com/gallery2 and it works with no problem.
After this I downloaded the gallery module and modified in the path part (but I cuold have done some mistakes).
I activated the module and the blocks on the administration part of drupal but the result is that the bloks doesn't show on the mail page, and if I click on the gallery link it doesn't run.
Below, the module configuration and the error.

Any suggestion?

Thanks.

Part of Module configuration:
function gallery_settings() {
$output = '';
$output.= form_textfield(t('Location of Gallery2'), 'gallery_dir', variable_get('gallery_dir', 'gallery2/'), 64, 64, t('/home/web4cu/public_html/'));

Error in browser:
warning: _gallery_init(gallery2//embed.php): failed to open stream: No such file or directory in /home/web4cu/public_html/dblog/modules/gallery.module on line 233.
