Slickr Flickr is limited to displaying only the 50 most recent photos from a photoset – This restriction is removed if you purchase Slickr Flickr Pro
Displaying Up to 20 Photos in A Set Using Flickr RSS
If you want to display 20 photos or less from a set then you can use the simpler format. You can get the set number from the end of the URL of the set on Flickr
[code]slickr-flickr type="gallery" search="sets" set="72157624473011937" items="14"[/code]
Experiment to Display More Than 20 Photos in A Set Using the Flickr API
Firstly I saved my Flickr API key in Slickr Flickr Admin Settings, then tried to display all 21 photos in the photoset. In the example below I decide to use larger thumbnails – 60% of small (240) = 144px wide.
[code]slickr-flickr type="gallery" thumbnail_size="small" thumbnail_scale="60" search="sets" set="72157624473011937" items="21"[/code]
Note that all 21 photos in the photoset are displayed.
If you specify a number of items that is larger then 20 and your have saved your Flickr API key in Slickr Flickr Admin settings then Slickr Flickr will use to the Flickr API to fetch photos rather than the Flickr RSS and this means that you can fetch up to 50 photos at a time.
Slickr Flickr can display up to 50 photos in the Standard edition and an unlimited number in the Slickr Flickr Pro edition.
