Instagram introduced Carousel of Images and Videos back in 2017. When you find something cool and you want to Repost them, you can simply use repostpro.app.
You'll just need to get the app here, then from the interested post > a simple tap on the three dots > Link, that's it! Open the Repost app they will appear instantly on the first page.
Now you'll be able to Repost them giving credit to the original author.
