This is a great product and so far all going great. I have tried ti setup the site branding and that is easy to change and add the business logo, but when I add an image (of the right size) to the login dialogue box it does not work and just remains saying Novell Filr. It is a png file that works prefectly for the banner along the top.

I have checked the documentation and that tells me nothing about what I am doing wrong. If I set it to NONE then it dissappears but then if I select any other image it only shows Novell Filr.
