i am having the same exact problem. Everything used to work fine, but i think after i installed better wp security plugin, it changed something and now it wont display any images on any movie. My cache and image dir is writable.
It scrapes all the other information fine (movie name, actors, plot, etc) but no image shows up, instead i always get the "no pictures available" gif. I tried uninstalling the wp security plugin but that didnt fix it. I also noticed an error that shows up on some of my other pages:
Warning: curl_setopt() [function.curl-setopt]: CURLOPT_FOLLOWLOCATION cannot be activated when safe_mode is enabled or an open_basedir is set in /var/www/vhosts/...
Does that have anything to do with why the images arent showing up?
Thanks for the attention and thanks for the great plugin.
