How to upload multiple photos at once onto Facebook from an iPhone 5?

Everytime I use the obvious built in feature for Facebook, it only uploads one photo at a time, one photo per post. So I was wondering how to upload lots of photos at once, in one post, thanks in advance!

There's an application you can download for that. Just search Facebook upload on the app store because I forgot the name.

  • Why is my Facebook account logged onto multiple devices? I was just randomly checking my account settings and was looking at devices that are logged onto my Facebook and it shows multiple devices, all from iphone 7plus which is what I have. This might be a stupid question, but wouldn't it just say iphone 7plus once if my phone is the only one logged onto Facebook? On my account settings, it shows 5 other iPhone 7 plus. Does this mean someone else is using my Facebook? I'm just really confused.
  • Why can't I upload photos to Facebook from my iPhone 3G? So I have an iPhone 3G, and the browser I use is Safari. Whenever I try to upload a photo to Facebook, it says the browser doesn't support uploading photos. My phone doesn't let you change browsers, so what can I do?
  • Upload photos from iPhone to Facebook? Probably a really stupid question but I'm trying to upload photos from my iPhone to my mobile uploads album on Facebook but whenever I do rather than grouping them together on my timeline like everyone elses they seem to be showing up one at a time despite having selected them all and taking up my entire timeline. Is there a way to stop this?
