I have the same problem : pictures not show...
=>
I insert images in image field, so in the module parameters I let "image"... is it right ?
In frontend, the module don't show imageq, just a default icon for a broken link... and if I ask the image's url I can see there is a problem :
- the module tries to get the image from the absolute pathway, at the root level of my hosting, not at the level where joomla is installed.

I have this value :
www.wiiplayers.fr///homez.303/wiiplaye/www/cache/mod_sj_zoo_slideshowii/02a79ab4d87bcbefc93bbb2ffd396c2c.jpeg

but my website is inside the www folder
and there's not a mod_sj_zoo_slideshowii folder inside the cache folder

Thank to help me.
