Forum Changing the forumhead background

[محروم.كوم]

Hello,

I am trying to change to forumhead background from this:



to this:


I sliced the picture above into 3 pieces:
Which is going to be on the right side (RTL forum)
Which is going to be repeated in the middle
Which is going to be placed at the left end of the bar

I tried to edit the forumbits.css but with no luck at all, maybe you can help me figure it out?

Thanks __DEFINE_LIKE_SHARE__
