Paths do not run as if you were to do them in wordpress etc.
You can run into issues with images and file sources like CSS doing ../ etc.
The best and easiest method is to ensure images and files all start with a slash src="/images....
Then you need to look at your image and folder naming:
With the web as it is, to avoid any validaility issues with browsers, file rendering, uploading etc you need to name folders and files in a certain way.
Folders and files need to be all in lower case, no spaces ( use a - ) and no funny characters.
The other thing is to ensure your files are not to big, optimised for the web and uploading correctly.
Tick all those boxes and you should find you wont encounter the issue or/and similar issues with images and files and folder paths.
