folder - DRopbox API - Best/Fastest way to get a link to an image -

my code attempting retrieve images , display them. have code uses dropbox api code, calls searchfilenames("/my photos", ".jpg", 50, false), returns @ least 50 results. need width & height, each of returned items, need call getmetadata() retrieve information, far good. need link image file can use display thumbnail. 50 results need 50 times, such createshareablelink() or createtemporarydirectlink() - issue takes long. tests 50 items run somewhere close full minute - slow. @ getfile() that's same minute range. maybe api call link in 1 call faster? looking faster way direct link image in dropbox folder? appreciated -

these steps take link image:

• https://content.dropboxapi.com/2/files/upload
  • response
  • get , store path_display response json
• https://api.dropboxapi.com/2/sharing/create_shared_link_with_settings
  • request
  • set path param path_display upload call
  • set settings { requested_visibility:"public"}
  • response
  • you url parameter, share link. if give end on dropbox page
  • if append url &raw=1 (maybe ?raw=1) link users end directly on image, rather on dropbox page. useful embeding <img> src attribute.
