When browsing Instagram, be it your timeline, popular page or through hash tags it doesn't take long to find terrific photos (and maybe videos). Remembering who posted the content isn't always as easy. Thankfully, Instagram has made it possible to view every photo or video you've ever liked; you just have to know where to look.
iMore originally posted this quick tip, and to be honest, it's one of those tips that's so obvious it's easily overlooked.
To view your like history on Instagram, in either the Android or iOS app, launch the app and then go to your profile page. From there tap on the settings icon in the top-right corner of your screen. Select Posts You've Liked.
You can now view and browse all of the posts you've liked on Instagram in chronological order. On iOS the layout is customizable, just as it is when viewing a users profile. Android users will have to browse using only thumbnails.
