On your Instagram feed, you can like, comment, and message posts. You can also save them, using the ribbon icon in the right corner. When you tap it, you’ll see Save to Collection pop up along the bottom of the post. If the image or video you’ve saved falls into a collection, such as UGC content or inspiration, you can create a collection for that content.
Keep in mind that when choosing photos to repost to your account, it’s important to stay aligned with your theme and aesthetic. You’ll want to choose photos that are a natural fit and have a similar color scheme and editing style to your own feed. When someone is looking at your Instagram feed, it shouldn’t be too obvious which posts are yours and which photos are UGC that you curated.
