I see, this really needs your SCREEN NAME, not Flickr ID.
This did NOT work taking the Flickr ID from here:
https://www.flickr.com/photos/myusername/
When choosing the Galleria option, I receive a bunch of error messages:
Could not extract width/height from image: http://farm4.static.flickr.com/3911/15361774315_e28fbdc08c_m.jpg. Traced measures: width:0px, height: 0px.
Inspecting the image errors further, it looks like it has issues getting the thumbnails.
First of all, it’s not even trying to get the thumbnail size, rather it’s calling for the full size photos instead and using them as thumbnails inside the div galleria-thumbnails
