[Plugin: Multiple Featured Images] No featured images box in admin area

Hello!

I’m using your plugin but nothing works…

Can you help me ?

I’d like to add up to 8 featured images for a post or page.
I’ve install the code in function.php of my theme and the rest in single.php.
I use “Portafolio theme” from WPExplorer(here to download: http://dl.free.fr/tuFMWiFre). Maybe it have to put the code in a special place…?

Thanks a lot for helping me.

Julien.
