If you wish to use an image pixel to add users to your audiences, you can easily do this by exporting an existing audience to an image pixel.
First, make sure you've created the audience you want to use as an image pixel.
Once the audience is created, head to Manage-> Audiences.
Find the audience you want to export and check the box next to it:

Note: Exporting your audiences as an image pixel is an Enterprise only feature. If you are interested in joining our Enterprise program, please contact ads@sharpspring.com.
