Random box click to main gallery

Edit the random block module and replace the url part with the url to your gallery.

I don't see where to do that.

Im useing gallery 1.5

I dont see anything like that.

1.5
I see now it in this part
//Print album name and link
switch ($showaname) {
case 1: //Classic Style
$row['content'] .= "<br><center>Album: "
."<a href=" .makeAlbumUrl($album->fields["name"]) .">"
.$album->fields["title"]
."</a></center>";
break;
case 2: //Petkov Style
$row['content'] .= "<center>"
."<a href=" .makeAlbumUrl($album->fields["name"]) ." title=\"Visit the album\">"
.$album->fields["title"]
."</a></center>";

I should get 1.5.3 uploaded tonight or tomorrow.
