on March 6, 2010 in WordPress with 2 comments by

Version 1.0.3 has been released, which fixes a few minor bugs and introduces a new option. It is still considered to be in a Beta stage, which most likely will change with the next release.


  • A new option has been introduced to hide the license and attribution information in the footer.
  • Bug fix: Config hash file was never initialized
  • Bug fix: Enabling “cacheable” option resulted in fatal PHP errors in some cases
  • Bug fix: Preview option did not work when “cacheable” option was enabled
  • Bug fix: “All Rights Reseved” licenses had no URLs

In addition, WP Flickr Background is no longer compatible with WordPress version 2.8 or older.
