Hi,
came from Jekyll (switched after two weeks for Hugo and never regret it).
I got your Foldergallery running. OK the DOM elements are created but the images are not loaded. Tried a little bit with the .PageURL but didn't get the URL pointing in my folder directory.
What therm do i have to search for, the Hugo documentation is a mouthful... ;) ???
I would suggest comparing the src attribute of dom elements (imgs) against the actual path of the images in the public folder
This is cool. I tried building a vacation image site using this... while I was on vacation, and failed. Wondering if there is a "complete" implementation of this code somewhere in Github or a similar repository?
That's pretty cool. I'll have to give this a shot.
