In order to place images on any NationBuilder page you must first upload them to the page (this also applies to email blasts). Go to the page you want to add the image to and click on the files tab. Any files tab in NationBuilder allows you to upload images from your computer directly to that NationBuilder page or email blast. 

Once you've done this you still have to place the images where you want them on the page. Go to the content tab   and click on the Insert/edit image button which looks like a picture of a tree. You'll get a insert/edit image pop-up on your screen. The second field down is Image list; from here you'll be able to choose from any images that you uploaded in the files tab for this particular page only. 

Ideally you should make the image the size you want it prior to uploading it. But when you click the insert/edit image icon on the content editor toolbar, you can also resize it by changing the dimensions.

The vertical and horizontal space is the amount of space (measured in pixels) you want between the image and anything else on the page. This is usually used to provide space between text in a surrounding article and an image.

To add an image or video to the top of your blog (above all blog posts), click on the files button while editing the blog page and upload your image. Next, click on Template, and under <div id=“content”>, add <div class=“padbottommore”><img src=“filename.jpg” /></div>. That will add a little padding underneath the image and your first blog post as well. To add a video, you can just grab the embed code that YouTube or Vimeo gives you and paste it in the same area.

In this clip from NationBuilder Live, VP of Community Adriel Hampton walks through the Australian Road Trip to End Poverty website to show how the combination of compelling images and a clear call to action encourage engagement.
