[ Moderator note: moved to Fixing WordPress. ]

Hello,

I’ve been tying for hours to replace the background of a slider on a home page by this very cool effet :

In the database,
I tried replacing the image link from the slider here http://test2.3angles.asia/
by the html come from this file : http://test2.3angles.asia/triangles2/triangles2.html

I don’t know if that’ the right thing to do but it didn’t work anyway 🙂

Any idea how to do that ?

Thanks a lot for your help
