Show photos per Sets

Yes,
when you
Add Gallery
you have to choose
Gallery Source: Photoset
Now you can choose from all your photo sets.
There’s a list of all your sets when you were asked to choose from:
Select Photoset:

Hope this helps.

sorry, I meant it is possible to display on a page all Photosets

You can display more than one gallery on a page or in a post.

So you can create galleries from each of your photoset and insert the gallery codes in posts or pages to display the Flickr galleries.

[RFG_gallery id=’1′]
[RFG_gallery id=’2′]
..

This way you’ll have many galleries in one page or post. For each of your photoset you’ll have one gallery. I think this is what you want to achieve.

You currently can’t do this automagically.
With [RFG_gallery] you can use your photostream – but that will not be group into galleries (for each photoset) like in the solution shown above.

Hope this help.
If this is not what you are looking for, feel free to contribute a detailed feature request and describe the exact behavior that you want at github. Maybe other authors like the idea and will spend their time to make it come alive. It’s open source.

I (or rather my client) would like the same as Azerty514. My client as requested something similar to this: https://www.fullwoodhead.co.uk/Gallery.asp
i.e. a gallery of sets.
Is this possible?

You need a (hierarchical?) representation of your flickr SETs?
Like it’s done by flickr:
https://www.flickr.com/photos/lars-schenk/sets

What should a click on a set do then?
Display only that single picture – or step down into the set and display that set as a gallery?

If you need a gallery inside a gallery (of sets) as in the example that you showed, I have to say that it’s currently not planned to implement such a rather complex solution.

Currently a gallery with RFG is only one dimension (that can be paginated) but is not hierarchical.
