Error 404 - images not found

Hi there!

Im just starting at git, obviously.
I’m currently trying to upload my first project ever. But I am having an issue by not seeing some images I’m uploading. IDK why and it’s driving me crazy.
I’ll leave the page here, anything u could help me with will be GREAT.

Si quieren escribir en español me da igual!

Thankssss and
Graciassssss
