on 1 computer login is no problem, other computer is there the message, you are logged in, but you don't see the pictures
Theme is zpArdoise (I do'nt want to change this)
How can I fix this?

What type of login? guest user? User account and with what righs? Perhaps the images are unpublished then they might not be visible unless with appropiate rights.

Note that you are on an outdated Zenphoto 1.4.14 from 2017. Please upgrade as whatever we tell here is based on the current version.

I updated the version Zenphoto versie 1.5.8

It is a guest user

Rights: view fully photo (I translate from dutch to english)
View gallery, these are the only one that is checked

You have most likely unpublished the image so the guest user can't see them. Please check the status of the images. As a full admin you always see everything.

but some people can login and see the pictures and others not, All logged in

I really can't tell. If it is all the same guest user there should not be any difference. If you have rights assigned it is not a generic guest user.actually.

I checked acces to all in album rights and now it works

Be sure to check not too much rights to provide unwanted more access than necessary. https://www.zenphoto.org/news/an-overview-of-zenphoto-users/
