Jsmug will hang for about 15 seconds, then produce a page with no headers from joomla, image placeholders and this error:

Warning: array_keys(): The first argument should be an array in /home/content/t/r/o/****/html/j/includes/pathway.php on line 63
(I've replaced our website name with ***** in the error above.)

Boxes as image placeholders appear so JSmug was able to retrieve a photos list, know the # photos and the proper size/orientation, but the images are not there (red X inside boxes).

On a different smugmug album, jsmug works fine. Not clear what the issue may be.

using Joomla 1.x - not the 1.5 beta.
