I am wondering what kind of license would be required to make instagram templates incorporating stock images and selling them on etsy for others to use on their social media.
This is an example: [moderator deleted possibly harmful or spammy link. You can post a screenshot.]
It would seem that would require an Extended License per the chart on the page linked below because you are using the asset in a product you will resell.
Asset may be used in merchandise, templates, or other products for resale*
