Broken Image

Hello,

I am using the Twenty Eleven theme for my website. I have created the child theme and made modifications to it. But somehow on my main website, the images seem to be broken, even under dashboard > header settings. Whereas the same theme works perfectly fine in my subdomain.
I tried completely reinstalling the theme as well as completely reinstalling wordpress but to no avail. I also checked if the images are available in the named folder. They are present but the browser always shows broken images.
My main website is https://www.gayatriagencies.co.in/salsemen
Subdomain where the theme works : https://www.statements.gayatriagencies.co.in
Please help.

Thanks.
