Hi Jos,

I found that Gallery doesn't show images when using pretty urls (internal or
mod_rewrite) because Gallery mixes up paths and URLs. (and also ignores the
paths and URLs from config as described in feature request #7081).

As a solution I introduced a couple of new class functions to Gallery_utils,
which build a full path or URL from a given relative path and the config data.

	public static $galleryPath = null;
	public static $galleryURL = null;
	public static $galleryThumbPath = null;
	public static $galleryThumbURL = null;
	public static $galleryPathSetup = null;
	
	public static function GetGalleryPath($path = '')
	{
		self::SetupGalleryPath();	
		return self::$galleryPath.'/'.$path;
	}
	
	public static function GetGalleryURL($path = '')
	{
		self::SetupGalleryPath();	
		return self::$galleryURL.'/'.$path;
	}
	
	public static function GetGalleryThumbPath($path = '')
	{
		self::SetupGalleryPath();	
		return self::$galleryThumbPath.'/'.$path;
	}	
	
	public static function GetGalleryThumbURL($path = '')
	{
		self::SetupGalleryPath();	
		return self::$galleryThumbURL.'/'.$path;
	}
	
	public static function SetupGalleryPath()
	{
		if(!is_null(self::$galleryPathSetup)) {
			return;
		}
		
		global $gCms;
		$config = &$gCms->GetConfig();
		
self::$galleryPath =
realpath($config['image_uploads_path'].'/'.DEFAULT_GALLERY);
		self::$galleryURL = $config['image_uploads_url'].'/'.DEFAULT_GALLERY;
self::$galleryThumbPath =
realpath($config['image_uploads_path'].'/'.DEFAULT_GALLERYTHUMBS);
self::$galleryThumbURL =
$config['image_uploads_url'].'/'.DEFAULT_GALLERYTHUMBS;
		
		self::$galleryPathSetup = true;
	}

Therefore two new constants are defined in the main module file additionally:

define('DEFAULT_GALLERY', "Gallery");
define('DEFAULT_GALLERYTHUMBS', "GalleryThumbs");

Now I modified action.default and sort out, where a path or a URL was needed.
All other methods and files need be changed too. But for now Gallery works with
pretty urls.

Finally the templates needed to be adjusted:
- Removed escaping of slashes by smarty.
- Added a preceding slash to javascript urls.

Do you want me to commit the changed action.default?
