Customise Login/Logoff screen

[zuessi]

I would like to change the picture above the login fields by a custom picture (like company logo or so).
It would be great to be able to choose a picture within the settings section.

Thanks for your great work!

This is best accomplished by a plugin. Would just have to over the css for "cactiLoginLogo".

Thanks for the swift reply.
Is there anywhere a "how to" or a "manual" for the new plugin architecture?
I failed to find some useful information.
