Imgur now blocks several VPNs and have issues loading embedded previews in several fediverse platforms. So instead of using imgur, you could use one of the following alternatives for uploading your images.

https://imgbox.com/
https://imgbb.com/
https://www.imagebam.com/
It’s for image too
yeah, i mostly use it for images and pdfs. it has been great when you need to send your friends some low size file at the eleventh hour.
