Hi all and especially Acrylian. Can the flash slideshow play a background audio file (basically music) simultaneously with the jpegs? If so, how is it done and can a separate music file be specified for each (sub)album? If not, can the jQuery slideshow do this?

No, none of the both modes are able to do that.

As ever thanks for the swift response. It is almost as quick as posting a query and clicking the browser's "RELOAD" button.
