multi-gallery error

Hi,

Basically, I think showing multiple galleries at the same doesn't work?

I'm trying to display the full content of several posts in a taxonomy view (i.e. the nodes with their galleries), and getting the following Warning: Invalid argument supplied for foreach() in image_style_create_derivative() (line 869 of [site address]/modules/image/image.module).

Weirdly: If only one of the node items in the taxonomy list has multiple images (and the others have single images), then that first gallery works ok, BUT the other nodes just show the gallery navigation rather than the single image.

any suggestions would be very much appreciated! as an aside, I'm actually trying to create a views slideshow of the nodes rather than a long list but thats just complicating things at the moment.

can't tell if this is a related issue?! http://drupal.org/node/1243114

cheers,
