Digikam export to Gallery2 embedded?

This is probably a silly question, but I see lots of people exporting to Gallery2 with Digikam and other Linux apps that use kipi-plugins, and I'm having a problem. It's not accepting my login, and I wonder if it's because I have Gallery2 embedded into Wordpress? I gave it the url to my Gallery2, but that's the non-embedded version, and it automatically puts a main.php on the end, so I'm really not sure what I'm supposed to do. What url should I be using?

I *think* the login is correct, as it's the one I use for Wordpress, and AFAIK, Gallery2 uses my Wordpress users. It's been so long since I installed Gallery2 and had to mess with the admin stuff, that I'm not even sure. I can login to Wordpress and thus get into Gallery2 admin no problem, and under Windows I can publish a folder via XP (using the plugin for that).

So what am I missing here?
