Only ten photos are showing on your site because Flickr is displaying ten photos when we visit your tag page http://www.flickr.com/photos/[email protected]/tags/alexsposa/
Either your other photos have not been made public yet by Flickr, or perhaps they are marked as private.
If you have set up your Flickr Authentication Token and Secret in Slickr Flickr Admin you can try adding private=”on” to the Slickr Flickr command – this should give you the full set.
