Two ways (only) to reliably add images into test questions

1. Use the Insert/Edit Image button in the Text Editor

Images uploaded using the Insert/Edit Image button are stored in the root level directory of the course’s Content Collection.

2. Use Respondus

Images inserted into questions using Respondus and then uploaded to a Blackboard course are stored in a root-level (https://bb.its.iastate.edu/courses/1/) directory with file permissions for ANYONE to view in current or future copies of the course. That means links to the image files should remain the same and should not break when a course is copied. (Respondus is a Windows-only tool used to create and manage exams, quizzes, surveys, and self-tests that can be printed on paper or published directly to your Blackboard course.)

However, once uploaded via Respondus, you can acess the images—but not the folder in which they are stored. So images cannot be added to or deleted from the folder.

If you need to edit or change an image in a question after it has been uploaded via Respondus, it is best to just edit the question in Blackboard, delete the incorrect image and add the correct one using the Insert/Edit Image button (see Figure 1).

 


The nature and cause(s) of image visiblity problems

Occasionally images in test questions are not visible to Students — and may or may not be visible to Instructors and TAs

Causes

  • The image was originally inserted in a way that Blackboard did not intend or expect.
    • For example, links to images added to a question using the HTML editor will break when course is copied.
  • Copying and pasting an image into a test question will cause problems.
  • Copying and pasting a question or a test from a different course will cause problems.
  • The link to where the image was stored is broken, even though the image was inserted correctly.
    • The image may have been deleted from the course’s Content Collection.
    • This may result from an error that rarely but occasionally occurs when a Bb course is copied from a previous semester.
  • The link to the image points to where it was stored in a previous version of the course. If this is the case, the question will appear fine to the Instructor (who has permission to view files in the Content Collection of the previous course), but Students in the current course will not be able to see the image because they do not have permission to view files in the previous course.

 


How Instructors can check test questions to make sure Students are able see images as intended

You can go through the test as a Demo Student (not Student Preview mode).

NOTE: The Demo Student is not the same as Student Preview!

 

If your test DOES NOT contain Question Sets or Random Blocks of questions from a Pool:

  1. Make sure your Demo Student is not enrolled in previous versions of the course. Unenroll Demo Student from previous versions of the course if necessary.
  2. Edit the Test Options (see Figure 2).

  3. When deploying the Test in your course, use Test Availability Exceptions to give your Demo Student access before the rest of the students (see Figure 3).

  4. Log in with your Demo Student account and take the test. If you see the images, other students should also be able to.
    Your test should be good to go.
  5. If you discover a question where an image does not display correctly, you must log back in as Instructor, and Edit the Test and Edit the Question (see Figures 4 and 5) and reinsert the image (as shown in Figure 1).

If your test DOES contain Question Sets or Random Blocks of questions from a Pool:

  1. Make sure your Demo Student is not enrolled in previous versions of the course. Unenroll Demo Student from previous versions of the course if necessary.
  2. Edit the Test Options (See Figure 2).
  3. When deploying the Test in your course, use Test Availability Exceptions (see Figure 3) to give your Demo Student access before the rest of the students. (This can be done at any time using Edit the Test Options.)
  4. Edit the Number of Questions to display so that it is the same as the Total Questions so that your Demo Student will evaluate the entire Question Set or Random Block (see Figure 6).

  5. Set the Test Presentation option to All at Once. Uncheck Randomize Questions (see Figure 7).

  6. Log out as Instructor and login with your Demo Student account and take the test. If you see the images, other students should also be able to.
    • If you do not find any image display problems, proceed to step 9.
    • If you discover problems, keep track of which questions had problems, then follow steps 7 & 8.
  7. Login as Instructor and Edit the Test (see Figure 8).

  8. Find the questions where images did not display correctly to your demo student, Edit the Question(s) (see Figure 9). and use the Insert / Edit Image button to add the image (see Figure 1).

  9. REMEMBER: When finished editing the questions, be sure to Edit the Test to change the Number of Questions to display as well as the Test Presentation options back to the desired previous setting(s) (see Figures 6 and 7).
