Your code looks for the images in a folder called geometry (at least the one I did check), but there's no such folder inside your public_html folder, where the server looks for it based on the code on your page.
There is such a folder directly on your root of the account though, so if you move it inside the public_html folder the images should work. Same applies for any other folder with contents that should be displayed on your site.
Also please do note that linux (which is the OS on our servers) are case sensitive, meaning image.jpg is NOT the same as Image.jpg, not sure this is relevent in your case, but putting it here just in case as another thing to check if moving the folder does not work instantly.
