Image 404 Errors in Frosty Theme

I am getting the following not found errors when using the Frosty theme:

I saw most of these not found images called from:
components/com_easysocial/themes/frosty/styles/style.min.css

It seems the relative paths in css files are wrong perhaps? I dont see any images folder in frosty theme. Its only in wireframe theme. Are these mistakes on the frosty css or is my ngx_pagespeed rewriting the wrong urls?

For the Last Error on the List: If you had noticed, ngx_pagespeed absolutify my css urls and it seems to cause an issue with the last image "../images/album-no-cover.png". How do I fix this? Do I need to retune my pagespeed or edit the relative path in wireframe theme?

PS: This is in my production site so I dont have a demo url. Hopefully the above info is sufficient enough.
