Instagram has just started testing and rolling out a new way to invite friends to join in on your feed posts. Now before posting your Insta carousel, you basically have to allow your followers to submit their own photos and videos that they may want to include. Of course you get the option to view and approve each and every photo/video submitted so that no nasty foot pictures (unless you’re into that) get uploaded by mistake. In the screenshot above you can see the ‘Add to Post’ option pop up on the bottom left of the image, simply click on that and submit your pictures. It’s an awesome option for friends to simply share the memories from the Goa trip that was magically executed or a simple night at the pub. But hey wouldn’t it be awesome to have a collection of all the cute pet pictures from every one of your followers?!
