    17 Change the `src` setting to `site/` followed by the name of your image file.  The `width` and `height` settings should be modified to match your image's dimensions (the Trac chrome handler uses "`site/`" for files within the project directory `htdocs` and "`common/`" for the common ones).

For example, if your project is named 'sandbox', and the image file is 'red_logo.gif' then the 'src' setting would be 'site/red_logo.gif', not 'sandbox/red_logo.gif'.

    6168Say you want to add a link to a custom stylesheet, and then your own
    62 header and footer.  Create a file {{{/path/to/env/templates/site.html}}} or {{{/path/to/inherit/option/templates_dir/site.html}}}, with contents like this:
     69header and footer. Save the following content as 'site.html' inside your projects templates directory (each Trac project can have their own site.html), e.g. {{{/path/to/env/templates/site.html}}}:

    92 Note that this references your environment's `htdocs/style.css`.

     100Those who are familiar with XSLT may notice that Genshi templates bear some similarities. However, there are some Trac specific features - for example '''${href.chrome('site/style.css')}''' attribute references template placed into environment's ''htdocs/''  In a similar fashion '''${chrome.htdocs_location}''' is used to specify common ''htdocs/'' directory from Trac installation.
     101
     102`site.html` is one file to contain all your modifications. It usually works by the py:match (element or attribute), and it allows you to modify the page as it renders - the matches hook onto specific sections depending on what it tries to find
     103and modify them.
     104See [http://groups.google.com/group/trac-users/browse_thread/thread/70487fb2c406c937/ this thread] for a detailed explanation of the above example `site.html`.
     105A site.html can contain any number of such py:match sections for whatever you need to modify. This is all [http://genshi.edgewall.org/ Genshi], so the docs on the exact syntax can be found there.

    106 If the environment is upgraded from 0.10 and a `site_newticket.cs` file already exists, it can actually be loaded by using a workaroud - providing it contains no ClearSilver processing. In addition, as only one element can be imported, the content needs some sort of wrapper such as a `<div>` block or other similar parent container. The XInclude namespace must be specified to allow includes, but that can be moved to document root along with the others:
     120This example illustrates a technique of using '''`req.environ['PATH_INFO']`''' to limit scope of changes to one view only. For instance, to make changes in site.html only for timeline and avoid modifying other sections - use  ''`req.environ['PATH_INFO'] == '/timeline'`'' condition in <py:if> test.

     220Trac caches templates in memory by default to improve performance. To apply a template you need to restart the server.
