Another Leverage Browser Caching F issue

Hi,

I have set up your plugin and the results have been pretty good on my GTmetrix stats.
However, it is still a F grade on the “Leverage Browser Caching” because of expiration not specified although the default delay on my .htaccess is one month.

I have noticed that this occured to many other users and you told them it was because of the “third part”.
I’m not sure about my website, there are some classical images on the report :
