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://postimages.org/
https://imgbox.com/
https://imgbb.com/
https://www.imagebam.com/
Do any of these have the ability to link an album? I often put multiple photos together, and post the that link to my communities.
Postimages support that. They will give a gallery link if you upload multiple files together. If you have a free account, then you can add or remove images from the galleries later as well.
Here is a gallery I made just now https://postimg.cc/gallery/pzt46sv
