Gallery shortcode issue

I posted gallery shortcode to a page, so that iit picks up pictures from posts and inserts them to the gallery. This works fine, but every post that there is no picture attached, it posts a blank image frame for the lack of picture.

[custom_gallery source=”cat=1″ link=”permalink” size=”200×200″ limit=”10″]. This is the code I input to the gallery page. Is there a missing parameter to ignore posts with no images?

Can anyone help
