WordPress 2.8.1 has been released. Unfortunately, the bug that affects one of Photo-Biyori functions hasn’t fixed.
Please read this post if you have a problem to get the thumbnail code into the excerpt field.

The milestone to fix the bug sets to WP 2.8.2. I hope WordPress team can make that happen with the next release.
