My Template

[sidotij]

All image sizes must be the same as in the original theme. Including the slider. Big slider: 1800x800 px, small slider: 920x720 px

At a certain resolution, images are not displayed on the small slider. Only text is displayed (heading).

It is also possible that this is due to the fact that you made changes to the template code.

I went back to an unedited copy of the template and I see that is the behavior
All good and thank you for looking at it.
