Simple question: why sample slide show don't show images that I connected to datasheet?

I created a slideshow using the “Add Element” option. I saved the images to a database. I connected the slideshow to the database. It appears -sometimes- connected in the edit page, retrieving images from the datasheet, but in the test site, it only shows the slideshow as elements I added. What am I doing wrong?

What I’ve tried so far
I asked gemini so mentioned about “sandbox”, “database is not live” etc. I couldn’t find something about it.
