Based on your provided screenshot, we can understand that it’s an image extention issue. Because a server is always case sensitive.
In your screenshot the image extension shows
.JPG (capital letter/uppercase) but in the code, it has
.jpg (small letter/lowercase). Now you have to change either the code to
.JPG (capital letter/uppercase) or the image extension to
.jpg (small letter/lowercase) to fix the issue.
