I am making an app which intakes students details that are entered. The student is able to view their record by retrieving their details from the database. I have coded all of these so far...but now I am stuck at assigning an image to each of those student records as they appear when the student selects to view the records. I have looked online but can't seem to find much information related to the database...
Below is the question from my assignment which I am stuck at:
"Provide an interface and corresponding actions where user can select an image and assign the image to a student. The images can be manually stored within the app itself. The app should be able to display the assigned image when showing the student information."
I have also attached images to make my question clear :)
How the images are meant to appear
