Seeking current media manager plugin (WP 3.91)

Hello all,

We are professional photographers who are in the process of migrating our site to a WP platform and are well along in the process. (Theme installed, sliders working, etc.)

The challenging part: we have close to 1000 images we need to upload and distribute to the various sliders. These are all organized by folder on our local machines, and are ready to go.

I have been seeking a plug-in that will allow me to manage the content into a hierarchical/tree structure. The one plug-in I found referenced hasn’t seen any development in the last 5+ months, and doesn’t appear to be compatible with WP 3.91

I’ve spent hours combing through the WP forums but mainly found folks discussing why a tree structure is needed, but not actual solutions that are current, etc.

Thank you in advance for your help! We’re very anxious to get this rolled out.

Jerry
