rel=”canonical”

Welcome. I have a problem in the tag rel = “canonical”. When I go to the page with the gallery, the code is this tag on the page with the album, resulting in photos placed in the galleries can not be indexed by search engines.
Tag rel = “canonical” to the page:
http://yar-doma.ru/gallery/
But the gallery is located at:
http://yar-doma.ru/gallery/nggallery/fotografii/karkasnyj-dom-v-karabixe
How can I solve this problem?
