[xwiki-users] logo broken

Hello, I am having an issue where when i change the default logo, it shows the broken image icon until i login and then it shows up. I have tried the following - making the wiki public then uploading the image and proceeding to make it private - making sure the image is 220x80 and named logo.png - attempting to make the attachment public (not sure how to do this) - trying to find the file on my linux server (i might need to use filesystem attachment porter Would creating a new skin that is the same as the current one and then uploading the image do anything? I am running Xwiki 7.0.1 tomcat7/mysql on debian 7. I installed using the .deb package from apt-get.When i was running 7.0 I was not having this issue Any help would be much appreciated!
