I changed a value on Step 3 of the configuration wizard (or in config.php), but the change isn taking effect. Whats going on?
These values are defaults. They take effect for new top-level albums, but do not affect already existing albums. If you want to change the value of these parameters for already existing albums, edit each album’s properties. You can access album properties by logging in as admin and going into the album in question. Select “properties” from the “admin options” pulldown. Then, in the popup window you will be able to change the properties for that album.
