First things first, if you haven't already why not sign up? Or perhaps you just need to sign in?
Here's a brief introduction to some of the key parts of this site, how it works, and how to find what you need. There's a lot that can't be covered here but let's cover the basics for now.
The best and quickest way to find anything is to use the search bar at the top of every page. This works using keywords. Just start typing and hit enter after every word. When you've added up to three keywords or phrases hit enter again. It's that simple.
Another approach would be to filter out unwanted guff on the photos or videos pages using the button in the top right. This is a great way to narrow down your results by fields such as category, popular tags, orientation, and much more.
Just hit the UPDATE RESULTS button at the bottom and watch the magic happen.
Found something you like?... save it for later by adding it to a collection.
With guest access you will be able to group a load of photos and videos together and then ask for download access. You can also get a link to share with a colleague.
With editor or higher access you'll also be able to create a publicly sharable link for the collection. Anyone with this link can download all of the photos and videos.
