Below is included some custom HTML so that you can make the infowindow contain the original picture taken in Fulcrum associated with that point on the map.  It will look like this when you click or hover:

First, you need to choose click or hover from the infowindow tab in map view.

Second, at far right click on the custom HTML icon </>.  Delete whatever is there and insert this code, making sure that you use the correct datashare (ask professor).

<div class="cartodb-popup header with-image v2" data-cover="true">
 <a href="#close" class="cartodb-popup-close-button close">x</a>
 <div class="cartodb-popup-header-">
 <a href="{{photos_url}}" target="_blank" title="Full Size Photo"><img src="https://web.fulcrumapp.com/shares/DATASHAREGOESHERE/photos/{{photos}}/thumbnail.jpg" style="width:175px;" /></a> 
 </div>
 <div class="cartodb-popup-content-wrapper">
 <div class="cartodb-popup-content">
 <h4>Languages Used</h4>
 <p>{{languages_used_}}</p>
 <h4>Scripts Used</h4>
 <p>{{scripts_used}}</p>
 <h4>Features</h4>
 <p>{{features}}</p>
 <a href="{{photos_url}}" target="_blank">View larger version of image</a>
 </div>
 </div>
 <div class="cartodb-popup-tip-container"></div>
</div>

You can customize this yourself to include any of column from the database as a <h4>.

Please refrain as usual from publishing the email addresses of data collectors.  If you are using the created_by field anywhere on your map, then please customize the html also for the legend, so that you use pseudonyms.  You can do that by selecting the legends tab and replacing the emails with avatars:

When done, apply these and check to make sure your legend has changed.
