Get all shared links in specifick folder

Oh, it is sad!

So maybe eventually you can give me some advice, my situation is like:

I have images in different folders. In my application and I would like to display all images from specific folder, so I need 4 links related to each image, they are:

1. Direct link to original image (to put it into <img> html tag), something like this:
https://dl.dropboxusercontent.com/s/xre2lk78i61pctb/1.jpg?row=1
2. Direct link to cropped preview image with specific size (also to paste into <img> tag)
3. Link for downloading a file:
https://dropbox.com/s/xre2lk78i61pctb/1.jpg?dl=1

4. Link to Dropbox page

https://dropbox.com/s/xre2lk78i61pctb/1.jpg?dl=0

My solution was to receive shared links, and parse it to a format I need. Is there any other way to load such data from Dropbox?

Especially I am interested in loading direct links to cropped preview.
