We are in the process of making an e-commerce website selling our own established brand of makeup. However we would like to use the instagram API to fetch images that use a specific hashtag like #ourproduct.
What we would like to do with these images is have something like a gallery of "others who bought this" so that new customers can see content from our other customers before deciding.
Is this legal or violating the TOS of Instagram? I know Instagram says that users' images are "all rights reserved". But isn't it implied consent by using our hashtag?
