I have a problem with nginx/pagespeed module. The images cache-time is default 5 mins on first pageload.

First time: enter image description here

Second time: enter image description here

There are in my nginx.conf:

##
# PageSpeed
##
pagespeed on;
pagespeed FileCachePath /var/ngx_pagespeed_cache;
pagespeed Domain https://example.com;
pagespeed Domain *.example.com;
pagespeed MapOriginDomain "http://localhost" "https://example.com";


pagespeed LoadFromFile "https://example.com" "/usr/share/nginx/www/";
pagespeed LoadFromFileRuleMatch Disallow \.php$;

pagespeed XHeaderValue "Powered By ngx_pagespeed";
pagespeed ListOutstandingUrlsOnError on;
pagespeed EnableFilters extend_cache;

# image related
pagespeed EnableFilters rewrite_images;
pagespeed EnableFilters convert_gif_to_png;
pagespeed EnableFilters convert_jpeg_to_progressive;
pagespeed EnableFilters strip_image_color_profile;
pagespeed EnableFilters strip_image_meta_data;
pagespeed EnableFilters jpeg_subsampling;
pagespeed EnableFilters lazyload_images;

# code related
pagespeed EnableFilters collapse_whitespace;

# DNS related
pagespeed EnableFilters insert_dns_prefetch;

# JS related
pagespeed UseExperimentalJsMinifier on;
pagespeed EnableFilters rewrite_javascript;
pagespeed EnableFilters combine_javascript;

# css related
pagespeed EnableFilters rewrite_css;
pagespeed EnableFilters prioritize_critical_css;
pagespeed EnableFilters combine_css;
pagespeed EnableFilters outline_css;
pagespeed EnableFilters flatten_css_imports;

How can I modify the default 5 mins cache-time? How can I pass the images on first pageload via pagespeed module?

It didn't help:

    location ~* \.(jpg|jpeg|gif|png|ico|cur|gz|svg|svgz|mp4|ogg|ogv|webm|htc)$ {
        expires 1y;
        access_log off;
        add_header Cache-Control "public";
        try_files $uri =404;
    }

    location ~* \.(pdf|js|css|swf)$ {
        expires 1M;
        access_log off;
        add_header Cache-Control "public";
        try_files $uri =404;
    }

From docs

When PageSpeed fetches a resource via HTTP or HTTPS, it examines the Expires and Cache-Control headers to determine how frequently it should update its cache. When these headers don't specify a timeout, a default timeout of 5 minutes is used. To override this, specify:

pagespeed ImplicitCacheTtlMs implicit_cache_ttl_in_milliseconds;
