No original image found with 2.8, but working on the dev snapshot of 8 sep.

Hi.
I have a 5.10 version of drupal and have installed the 2.8 stable release of lightbox (with jquery update 1.2.6).
I just use this module for automatic gallery support with images loaded with the image module.

When I click on the thumbnails in the gallery view, the overlay shows the "brokenimage.gif" instead of the original image.
So I tried the Dev snapshot and it works now.

I've searched into the javascript of the 2.8 to find where the problem occurs, but I'm not really aware of the mecanism, so I've given up, I don't have enough time...

Has this happened for somebody else ?

Thanx for this module !
