I've just installed Zenphoto, created an album with subalbums, and uploaded several images to one of the subalbums. Everything there is working is great.

But I can't for the life of me figure out how to get audio files (m4a) to display and be accessible. I see that Zenphoto is supposed to support these, but I can't find any instructions for making this work either in the manual or in the forum. Maybe I'm just not lookingin the right place.

At this point I've uploaded (via FTP) a bunch of m4a files into the album directory where the images are. But none of the audio files appear in the web display of that directory. Can I get some hints on what to do here?

Thanks for any insight.

Okay, I've managed to get this working by adding a couple of appropriate plugins. However, the thumbnails for all of the mp4 files are identical. I'm perfectly happy with the graphic being identical, but each graphic has a bottom line that says simply ".mp4a". I've got the mouseover effect working so the title of the recording can be seen in that way, but is there a way to have the appropriate text label (say the filename) displayed on or below the thumbnail. I'm thinking maybe not without a lot of work. But worth asking.

Thanks.

You can also show the image title but you will have to modify the theme used. The basics:
