Full width image post displaying on Blog Page

Hello

First of all, congratulations on the plugins !:)

I´m experiencing an issue, i´ve used full width parallax image on a post
but when i go to the blog page, the image goes through out all the width of the page.

Is there a way to fix this ?

I would like the image to be like a thumbnail size instead, like a featured image.

I send you the links for you to check:

Thanks in advance for your help !

Kind Regards
