YouTube Video Gallery

[blacksword]

i have tried everything to add these xthreads but at the custom thread field there are things that i dont understand, i was trying to add the youtube video gallery but i really need some help with on how to install it the right way otherwise i get white pages on it.

im searching anything and i found a website called sharree.com and i want something like that, is it the same code or is it changed completely, cause i want things like that on my forums.
