I've  installed Album and I'm having trouble getting the thumbnails to work.

I've created a new album and added photos to it, but the photos in the album do not display their thumbnails.  Instead they say "(no thumbnail)".  Does anyone know why this is happening?

I found a solution that has worked:  http://forum.cmsmadesimple.org/index.ph ... l#msg43456

Is this the only way to fix the problem?  Is there a patch for this?
