photo album pages set to canonical url

In testing my site with SEO Doctor it has alerted me that my photo album pages are not indexed because they are set to a canonical url. The main photo page is alright, it is the albums themselves https://www.mysite/photos?shashin_album_key=19 which have url set to https://www.mysite/photos.

Anyideas on how I can (if i can ) resolve this?

thanks
