In the end the big code & user base of Group Office and the fact that it met all our requirements from the beginning made a clear winner. Please note: that the listed projects may have been updated in the meantime and features may have changed.

Note: The previous version (v0.1.3) introduced a new feature to configure the thumbnail size of your photos which is not included in the original one.

What does it? Exactly the same as the original one with the advantage it is also working with PHP4. In my opinion this is quite important as many users haven’t upgraded to PHP5 yet.

How to use it:

1. Unzip the archive to your wp-content/plugins/ folder.
2. Activate the plugin via the Plugins menu inside WordPress administration view
3. Now create a post or a page with KPICASA_GALLERY(YourPicasaUsername) as the only content. For example, if your Picasa username is knut123, you would create a post or page with KPICASA_GALLERY(knut123)
4. Enjoy!
