Duplicate content issue

[simonatkinsphoto]

I'm getting duplicate content warnings from Moz for various slideshows on my posts and pages in Wordpress. It seems when I create a slideshow it exists as its own page and as these have no text Moz sees them as duplicates.

Here are some examples -

http://www.weddingphotojournalist.co.uk/?gallery_page=slideshow&pp_gallery_id=1331991312
Moz says is a duplicate of - 
http://www.weddingphotojournalist.co.uk/?gallery_page=slideshow&pp_gallery_id=1000144730

The second of those two slideshows is on this page -http://www.weddingphotojournalist.co.uk/menorca-wedding/  but also exists as the page above.

How can i avoid these being seen as duplicate content?

Hi Simon,

WordPress isn't great at handling slideshows and paginated pages in order for SEO. What would be best to do is have a developer look into this and make sure that canonical URLs are added to the page in order to respect the duplicate content. There are as far as I know no out of the box solutions for this.
