i'm quite a beginner with wordpress, and i'm stuck with the installation of a plugin : Firstly, i tried the photo gallery plugin nextGen : http://wordpress.org/extend/plugins/nextgen-gallery/installation/
So, i tried another plugin : lightbox 2 : http://wordpress.org/extend/plugins/lightbox-2/
but after being activated, nothing appears, there's just a reference to it in the settings, but i can't see where the plugin is...
Quite frustrating ! If anyone could help me, i would really appreciate.
Thanks a lot
