Comments

When working with file icons I noticed 2 annoying things.
1) The file icons do not include alt or title tags
2) The src is a relative URL instead of a fully qualified URL so if you have a file icon being displayed in an RSS feed, when that RSS feed is displayed in someone's email the icon is broken because it does not include the domain name.

Here is a quick fix that can be used to address both of those issues:

function yourthemename_file_icon($variables) {
$file = $variables['file'];
$icon_directory = $variables['icon_directory'];
$mime = check_plain($file->filemime);
$icon_url = file_icon_url($file, $icon_directory);
return '';
}

Hope this helps someone looking at this hook and wondering how that might be done :-)
