I use BL with pleasure. I have created a travel photo album which contains images and text… etc…
Is it possible to create a functional export of this album, read-only, locally, on a computer, with a web browser?
You can install MAMP (https://www.mamp.info/) on your computer and run a copy of your Backlight installation. Then you can use a browser to access your locally hosted site. Once you have your site running, log into backlight admin and adjust the Site URL.
This is an advanced subject and might take a bit of time to get everything working. But once done, you use your local site as you do with you regular site. Hint: I highly recommend that you will change the color or another setting of your local site to make it obvious that you’re not using your standard site.
