To be honest, I'm not really sure we are all on the same level here. In the last post, you are speaking of the music "starting" and "not starting" -
The audio uses flash cookies to decide if it starts or not. If it is not the first time you are running the gallery, the music will only start if it was running the last time you viewed the gallery. If the music was stopped the last time you viewed the gallery, it will NOT start automatically. This is done because a user that STOPS the audio, most likely does not want to hear any audio next time.
However, these settings have nothing to do with the audio player actually being available or not in the top right corner. It will only display if "audio=true" or your internet speed exceeds the speed set in the config (Ex. "audio=24" require 24 kbit/s).
Another issue to consider, is the fact that Imagevue uses 'cookies' to remember the estimated internet speed. This is because after Imagevue has been run the first time, it gets cached, and Imagevue will not be able to detect the speed, so it has to use the speed based on the first visit.
If anyone has a link to an Imagevue gallery where "audio=true" in the config file and audio is not playing, then please show me the link.
Why would there be difference between browsers? Because browsers have independent flash cookies. Maybe the gallery loaded sufficiently fast in one, but not in the other ...
I have tested the links
http://www.keiner.ch/photos.html where audio worked every time for me(audio=true in config), and
http://raeonimages.com/upload/index.php where audio will not load because "audio=false" in config.
