You mean the title tag inside the <head>? Just put it in there yourself by using a text-editor or whatever. You only have to add it in the index.php file inside the Plogger directory. Or in other words, your Plogger template file.
Only the (nice) permalink/path to your album. It does that automatically.
If you also want the caption inside the title tag, take a look at the function plogger_head(); and function plogger_get_picture_caption(); inside plog-functions.php.
I think there will be a way to get the caption inside the $title.
