Sustained Investigation: Images

Sign In to the AP Digital Portfolio

For information on how to create and choose artwork for this portfolio section, visit Sustained Investigation Overview.

The Sustained Investigation section has two components: Images and Written Evidence. You can start uploading images in the Images tab as soon as you access the AP Digital Portfolio. You can always delete, add, or rearrange images later.

Important things to remember:

  • Select Save before exiting or switching from one portfolio component to another.
  • Only select Submit Final when you’re ready to submit the portfolio component as final to the AP Program for scoring. Once it’s submitted, you can’t make edits unless your teacher returns your portfolio component to you before the AP Program submission deadline. 


1. Open the Sustained Investigation page and select the Images tab.

You’ll see a template containing boxes with fields for information.

2. Upload images

To upload an image, choose a box in the template and either drag your image into the box or click Upload.

Identify the following for each image: 

  • Materials used (100 characters maximum, including spaces). 
  • Processes used (100 characters maximum, including spaces). 
  • Dimensions (height x width [x depth, if applicable], in inches). For work that is flat, enter 0 for depth, if applicable. For images that document process or show detail, enter NA. For digital and virtual work, enter the size of the intended visual display.
  • Image citation (100 characters maximum, including spaces). Provide proper attribution and/or citation of all pre-existing material. Formal APA or MLA citations are not required.
