Prevent showing image posts under blog posts as previous/next posts

Another question.
Underneath the blog posts, previous and next posts are shown in buttons. I would like to prevent image posts to show there, as they are not relevant. So only blog posts should be shown there. Does anyone know how this can be solved?

Example of where this is happening: https://eenlepeltjelekkers.be/tagliata-met-parmezaan-en-rucola/ (left button is the image post of the same content).
