Just going to state the facts here. Imgur has moved from being an image hosting service to an image sharing service. It is not aiming to take on Flickr or Picasa for personal photo storage. It has become a social platform focused on image sharing. We have seen few improvements for members using it as it as an image storage platform for a long time now. The entire development process is focused on the social component of the service.
I would however recommend an app named ShareX here. It has a feature named Watch Folder. You can set it to automatically upload any new photo added to specific folders to your Imgur account. It’s not perfect but it works for me. Cheers!
