Problem with the uploading

Hi! It's my first time that I make an html and, above all, that I upload it. I have a problem with my website.
Today I have uploaded all the files of my website (file.html; file.css, file.php and .js) at 3 o'clock. I uploaded them through the file management.
The problem is that when I go to my website, the browser tells me that there are missing elements/files and the website is made up only of writings, no images and other graphic elements.
Do you know what step I missed or what I have to do? Is it only a issue of time?
Thanks

It looks fine now, have you solved the issue?

Yes, finally I got it and it is good. Thanks!
