I used to use Imgur to host all of my images. Recently the app was updated so a share link no longer gives you a direct link to the image, but rather the image in an album link. You can remove part of that link and add a file extension And it still works, or you can use something else like catbox.
Before I joined Reddit I was very active on Imgur. I would still go back from time to time. But it really has gone to shit in the past few years. Ads that block content, play loud sounds, inappropriate ads.
