PROFILE PHOTO NO WORKY D:

I'm hella new but I at first had a ruby gloom profile photo and it worked but since I've customized my profile I wanted to change it to a silent hill pfp. I did and it is broken now like it blank. I tried clearing out my code then uploading different ones but its still not working :( if anyone knows how to fix this tell me I just wanna have a cool profile layout :3c
