Adding a new thumbnail. Doesn’t work...

Trying to update the gallery under latest shows. I have made a gallery page under the Dat Bolwerck. Clicking on it from here I have made a slideshow, but it doesnt seem to be published. I can only see it from this specific Computer. What did i do wrong? The settings are the same as the others(that are visible on internet. I don’t remember How or where i make the gallery image of this new one(see image 2)

hope somebody can help me.

Can you post your site url? And the password if needed to see it. This will allow others to help much quicker.

I don’t know if my question was clear, Hope somebody understands it...🙏

So I would like to add a project image on the same side as picture Nr 2, and by clicking it going in to the side with the slideshow that I added. But it doesn’t publish (is not there apart from on my computer)

so 2 problems, how do I add the thumbnail and why isn’t my additions, the new exhibition visible apart from on my own computer...?

This may sound like a dumb question but is the Dat Bolwerck page enabled in settings? If not, you alone would still be able to access it in config.
