My apologies if this has already been asked and answered, and also for my ignorance. I am new to Zen Photo, and not a developer. I am trying to figure out how to display thumbnails in my album rather than the slideshow. I am using the Effervesence theme if that is a factor.
Thanks,

There are theme options for that with Effervescence+. Change the "personality" option.

Excellent, many thanks for this great software!
