How do I back up my pictures on my Omeka Classic site, please?

[THS]

Hi @DanieleB, I’m still hoping for an answer to my last question, and also for this one. Thank you!

Can I scroll through my photos?

To see a photo, I have to click the thumbnail, then click the photo to enlarge it. Before I can see another photo, I have to click Back twice. Is there a faster way to view my photos, like in a Lightbox where I can scroll from one to the next? I’m using Omeka Classic with the Emiglio theme. http://topangahistoricalsociety.org/archive/
