Is it possible: Load thumbnail linked images in inline?

[pmgeuze]

When I look at the most of my feed articles, they are of a hobby where the poster will use a thumbnail of a larger image. I would prefer if the thumbnail link would instead open the source image at either 100% or the maximum of my RSS screen.

Example feed article: https://onelover-ray.blogspot.com/2026/01/zac-v-jason-argonauts.html

I have tried both CSS and JS custom code provided by AI but they do not seem to work or are dependent on reloading something (?). I wonder of there is someway to make an extension that works like the comics extensions that I see.

I hope that you can just point me in the right direction so I can learn my own solution, or to an existing solution so I don't reinvent the wheel by making a square.

Thank you.

Could you please provide a screenshot of your FreshRSS instance that shows the situation and which thumbnail you mean?
