Hi,
assuming that you`re using the default template and that the extension of the picture is .png and that the logo shouldn`t be clickable:
- put the image into dokuwiki/lib/tpl/default/images/logo.png
- edit dokuwiki/lib/tpl/default/layout.css
- search for:
div.dokuwiki .header {
padding: 3px 0 0 2px;
}
- and modify it like below:
div.dokuwiki .header {
padding: 3px 0 0 2px;
background: __background__ url(images/logo.png) no-repeat top center;
height: 100px;
}
You may have to play a bit with the height attribute to fit the height of your image.
