I uploaded 6 images but cannot display them in the post.
In the image/gallery manager, clicking on Show gives the insert page, but size is 0 x 0 and full size is the only enabled option.
Screen shot examples (found on mailing list): http://musing-minds.com/wp-content/uploads/2008/10/showclick.jpg
The generated image tags in the post look as follows:
<a href="http://www.example.com/images/2008/12/241.jpg" title=''><img src='http://www.example.com/images/2008/12/241.jpg' width='0' height='0' alt='' /></a>
Thus thumbnail images are not showing, but the lightbox gallery works. Using latest release 2.7
