It is compulsory in our app that you upload at least one picture for your activity to show users what your activity is about visually. That said, we understand it may be difficult to have a photo ready for usage. In that case, we recommend the following links to find stock photos for you to use. Please bear in mind that you must have the rights and the proper licenses to use stock photos, whether it’s from our recommended list or from other sources, so do make sure to read their terms and conditions properly. We are not responsible and are not liable for any improper usage of photos and images and the responsibility will be yours.
