Sometimes you get a webpage that only shows basic text with a white background instead of the graphics that should be there. What actually causes this and can it be prevented with better programming?
Normally if graphics is not shown then it is because the graphic image that is supposed to be there has either been deleted, or perhaps moved to a different directory.
I am not sure this can be improved by better programming, the only thing that may help is to make sure all graphics images are held in a folder called images.
Then at least you know where all the graphic images are (or supposed to be).
