Cache static content at D

[Ekspert]

Hello Evereyone
I have just tested my website https://ekspert-bankowy.pl and everything looks fine, mostly A and B, but the cache static content is very high at D, does anyone know what might be a problem ?
ThanksEkspert Bankowy

Hi, You have not set the cache time for your images long enough. Most of your images are set at 2-3 days. You need to set your cache-control expire time to at least a week on jpg & gif. An example is as below if your using .htaccess.

<IfModule mod_expires.c>
ExpiresActive On
ExpiresByType image/jpg "access 1 month"
ExpiresByType image/gif "access 1 month"
</IfModule>
