Files not uploading on my webpage on Netlify

Hey, I’m hosting my webpage on Netlify (HTML & CSS 3 course) but i have a problem, my files (pictures, icons) are not uploading, it’s like they’re non-existing. I’m using a GItHub repository to charge all the media, there i have all the files, everything is working more than just fine except that. Please, i’d like to hear suggestion and possible solutions for my problem, i know there’s something i’m not seeing and you can help. Thank you so much in advance.
