Uncaught TypeError: Cannot set property 'src' of null

The null is the important part. Your DOM search (getElementById) failed.

Some ideas off the top of my head:

  1. The script is running in a different page
  2. The tag is not actually there
  3. There is a misspelling in the id (looks good in your example though)

If you need an example to work off of: https://www.w3schools.com/jsref/prop_img_src.asp
