ngbSlide represents a single slide of the carousel which is having a <img> tag and a <div> with a carousel-caption class to add text on the slide image

I am trying to wrap my head around pulling images from a directory to use in this. I have a folder called “dogs” where I have all my dog code and then separate folders for each of my dogs pictures… basically I want to click on a link and then the carousel will show up all the pics for that dog. I understand I would have to create each caption etc for the pictures but for some reason it does not show the pics at all.

directory structure

Any help would be greatly appreciated.
