I wasn't completely positive how to add a header to generator but I came up with this (http://lay-of-luthien.livejournal.com/?s2id=17556617). Just copy and past the code into your layers and modify the colors/width/header image. Or if you want, you can tell me what you'd like, I can whip something up, and give you the code. You'd just have to add your own header link.
set page_background_repeat = "repeat"; set page_background_scrolling = "scroll"; set comment_bar_screened_bgcolor = "#000000"; set page_background_position = "top"; set box_top_margin = ""; set comment_bar_screened_fgcolor = "#a88d3e"; set entryborder_style = "solid"; set weak_text = "#a88d3e"; set page_vlink = "#a88d3e"; set box_width = 700; set stronger_text = "#a88d3e"; set page_alink = "#a88d3e"; set show_header_links = false; set stronger_back = "#59010d"; set comment_bar_one_bgcolor = "#000000"; set comment_bar_two_bgcolor = "#000000"; set comment_bar_one_fgcolor = "#a88d3e"; set entry_text = "#a88d3e"; set page_link = "#a88d3e"; set entry_back = "#000000"; set weak_back = "#000000"; set custom_css = "body { margin-top: 380px; text-align: justify; background-color: #000000; background-image: url(http://pics.livejournal.com/lay_of_luthien/pic/001k065k); background-repeat: no-repeat; background-position: top center;
