Background is not visible

The page source shows that the photo is present, but not visible in the browser. See screenshot.

Have you checked whether or not the image is in the (/images/clipart/photo/) folder?

yes i checked, the picture is in the folder

Are any of the letters capitalized in your pic?
For example pexels-andrea-piacquadio-37771842.jpg should show on screen but
pexels-Andrea-Piacquadio-37771842.jpg will not.

Everything is in lower case. When I make a test project with the same photo, it is visible, so there is a (small) problem in the program

Try the following URL and see if you can view the image:

Alternatively, try another one of the images that come with PHPRunner and see.

The url does not show a photo, not even in another project where the background photo is visible.
I solved it by changing the page color by changing the css code in the header :

Thanks for help.
