Hi Rocky,
Thanks for your order!
The header in Uniform contains the user panel, so by default, it's not possible to have a "full width" image. With that said, you can add this to extra.less to relocate the user panel into the "navigation bar" area:
Less:
@media (min-width: 651px){
.p-header .focus-wrap-user{
display: none;
}
.p-nav .focus-wrap-user{
display: block !important;
order: 1;
}
.p-nav .focus-wrap-search{
margin-left: auto;
}
}
Assuming you followed the installation tutorial correctly, you should be editing the second theme in that list (Uniform Light).
I should also note that I'm in Australia, so your above messages came through a little after midnight, and at 4:15 AM, hence the very minor delay.
