How to set the image thumb when sharing through facebook

[joie 4]

Hi Guys, I have installed this plugin Socialize at my site http://www.gspreschool.net When I tried the facebook like button. I notice that at my facebook page, the image thumb displayed is the pagelines leaf (the one at the very bottom) Anyway to change this to any image within my pages / blog ? Thank you, regards, joie

I can't find the facebook "like" button on your site, do you have the plugin activated now?

my bad, forgot to activate... Is there a way to set the thumbnail using relevant images ? Does it have to be a plugin or can i put a code somewhere in platform base php ? Thank you

I'm not sure how to change the thumbnail since it's something that just gets set automatically. You can try finding an alternative to the plugin, but you'll have to use code provided by Facebook.
