I'm using this plugin by Lennart Groetzbach to randomize the header, I also have Header Image Rotator by Matthew Hough as they both seem to work the same and even use the same directory, I don't currently have the second activated.
It previews ok with kurbrick theme but I'm using Platinum 1.0 and on that it seems to radomize the image but overlays the default image over the top of it. Can anyone explain why this happens, how to fix? Thanks
