You can add pictures to your online test questions in Blackboard.
To do so, go to the Test Manager and edit or create a test. Enable the pictures in questions option under "Creation Settings". Then create a question and browse to your computer to find the image to add.
The image must be appropriately sized, as Blackboard will not automatically resize the image. We recommend using images no more than 640 pixels wide.
Here is a video demonstrating how to add pictures/photos to online tests in Blackboard 9.
