I tried to solve the problem on my own, but I failled.
So I'm using a skin from this site it's vibrant natalie, then i wanted to add my own layout/header, i replaced the url, and wanted it to center and no-repeat, but aparently it doesn't work. can anyone tell me what I should do? perhaps I'm not puting my url in the correct place...
I see that there are similar topics here, but none of them as a proper answer nor solution to the problem.
please be so kind and help me.

if i could see your code, then i could tell you if you did it right.

assuming that you did, make sure you have a webpage url listed in your profile.

thank you so much
so here is the my header's url http://img.photobucket.com/albums/v255/Chr...pg?t=1164833803

could you please tell me where I should place it?
