Hi @Michiel,
In order for us to check the issue and provide resolution we would require to take a look at your site. In your query you have mentioned text for link to your site but it seems the link isn’t going to your site rather it is landing us to the screenshot you have added.
Could you please forward your site’s URL so we can take a look?
In the mean time, if you use a “Text” widget, add a title and add the image tag in the content it should work fine. We can provide more useful information after checking your site.
Thank you
Regards,
Support Team
