You can use the Page Builder on Posts, it’s just that we have it disabled by default. You can enable it under Settings > Page Builder > Post Types. Once this is done, simply launch the Page Builbder on your Post and add a Gallery module for your Smugmug Feed.
I hope I can still reply even though this is closed.
So I have to ask, why is RSS galleries/slide shows not a bigger feature. I feel like it is one of the best kept secrets and before I start using is as my source for pages and galleries I want to make sure I am not missing something or making a big mistake.
There are very few wordpress gallery plugins that even state they will support RSS galleries, I accidentally found it on BB, if this is a feature that really works we need to start promoting the ability BB has to help photographers.
Thanks for the kind words and glad you finding it useful! Agreed, we should highlight that a bit more and will most likely in a future site/marketing update. Thanks again and let us know if we can assist further!
