Solved!, you have to go to customization in the wp dashboard /wp-admin/admin.php?page=customization and in the tab Blog you will have to change
<a href="#"> replace this # to the address you want to take readers when they click on the image example //yourwebsite.com/linkofthepageyouwant/
<img src="//yourwebsite.com/locationoftheimageyouwanttodisplay"> here you put the link to the image you want to display
</a>
you can do this for both images, one shows at the top and the otherone at the bottom, if you want to display the images in mobile devices aswell have the icon checked and make sure you save before leaving!
