This plugin allows you to embed a Simpleviewer Flash Object integrated with a Flickr account.
Please check your height settings for the plugin. In Firefox a setting of 100% height only works if all parent elements also have height set at 100%. This seems to be the cause of things showing up blank when viewing a page or post with the plugin.
Please read the instructions located on the SimpleFlickr settings page. The process to authorize this plugin with your Flickr account is straight-forward you just need to follow the instructions.
This was an issue with the SimpleViewer flash applicaiton and has been resolved as of version 1.8.5. This version is part of SimpleFlickr version 3.0.
