No problems with languages now. Thank you very much.
Now avatars. There are 3 options in SMF: server-stored pictures, URL to an external pictures and uploaded by users. Server-stored pics and external avatars are shown without any problems. But if I upload my avatar to the forum I can't see it in the gallery. May be this issue has nothing to do with PhotoPost and I have to deal with the forum instead? The thing is that avatars are supposed to be uploaded to attachments directory but it remains empty. And image location looks like this http/scrapmuss.ru/forum/index.php?action=dlattach;attach=17;type=avatar
Here is an example: Inchovochka's avatar is external and located in picasa web album. Admin's avatar is uploaded to the forum. You can see both of them in the forum
Content visible to verified customers only.
In the gallery here Princess - My Photo Gallery
only Inchovochka's avatar is shown.
