i'm currently testing this plugin for a future project. i only need steam as provider and want to use this login button: http://cdn.steamcommunity.com/public/images/signinthroughsteam/sits_small.png
is it possible to customize the buttons? there is an image in the plugin folder called provider_sprite_35_35.png, but it seems that these buttons are loaded from OneAll.
i hope you can help me =)
