使用Laravel在服务器上上传图像

I've uploaded my website to 000webhost server. there is a problem of images it don't show up when I upload them. it was working fine while I'm on localhost I moved my public folder to public_html folder on the server but I can't create a symlink on the server I tried this line but it didn't work

symlink('/agroam/agroam/storage/app/public', '/agroam/public_html/storage');

Can anyone tell me why? or give me another way to make it works

Using 000web free hosting symlink is disabled that is why the line doesn't work. You have to upgrade to premium version so you can have SSH access to your account.
