Might depend on which frontend or app you’re using. On Boost I can just tap the attach image button to insert a direct markdown link with the file uploaded to sh.itjust.works. if you have the URLs, you could also insert the links yourself like [text](URL)
I’m either uploading them directly to the Lemmy instance or I use https://catbox.moe/, but there’s also https://imgbb.com/ or https://imgchest.com/
…can you upload more than one photo to the Lemmy instance? It only let me do one per post, unless I did it wrong.
