written by bmeredyk Since I had a hard time getting this to work, I thought I'd post some instructions for others.
Where to put files - this wasn't clear to me at all.
When you unzip the g2image package, you end up with a file structure like this:
tinymce_plugin/
tinymce_plugin/g2image/
wordpress_plugin/
CHANGELOG.HTML
CREDITS.HTML
README.HTML
(and a few other files)
