Here is something you can do. Right-click on one of the placeholders where an image should appear and click “Open image in new tab”. Firefox will open a new tab with the URL of the image and it will display any errors in loading the image in the body of the tab.
If you get a “file not found” kind of message, the URL of the image should be contained in the message so you can see where the browser is looking for the image. Based on that, you should be able to possibly determine what’s wrong and make the appropriate corrections.
Good luck!
@sharvin-shah thanks for your suggestion but i already checked that.
Did it give “File Not Found error” when you opened the image in a new tab??
