While Lemmy does not support image or video “albums” natively, you can add as many images and/or videos as you want to the post’s body (within reason).
It’s better to do this then create multiple posts if you have multiple images to post. Simply upload the main one as the URL and the rest in the body.
Please also mention that the post contains multiple media in the Title of your post, so that people know to open up the actual post to view the rest!

Install Tampermonkey on Kiwi Browser (if you’re on desktop, it’s also available on Firefox, not on mobile tho)
