What is a gallery?
For whatever you find interesting, fascinating, or mind-blowing on Flickr, galleries are a way to curate up to 18 public photos or videos of your fellow members into one place. It’s an opportunity to celebrate the creativity of your fellow members in a truly unique way around a theme, an idea or just because.
How do I make a gallery in flickr?
To create a Gallery just go to a photo or video that you want to add and click the "Add to a gallery" link within the Actions menu. From here you can create a new gallery or add the image to an existing one.
