Is there a plugin for a non-ordinary gallery or how to make it yourself?

Question

WordPress

Hey! The question is. The designer came up with an unusual display of the gallery. That is, several pictures are loaded onto the page, and they should become a slider - nothing complicated. But the unusual thing is that the thumbnails of these slides are "hidden" under the slider, and by clicking on the "All pictures" button they should appear.
Normal slider:
By clicking on "all pictures":
Dear Wordpress experts, please tell me if there is such a plugin for wordpress, or maybe one of the popular gallery plugins can be suitable for this, or how can I "finish" this functionality myself? ? The bottom line is that then from the admin panel it was just to upload pictures. (There should be 9 pictures in total) The level is average. So advice "to rewrite a script" unfortunately will not help.

Answer 1

Well, do you have pictures for scrolling somewhere in the markup?
1. click on "all pictures".
2. Add or make visible the container where we will shove all the pictures.
3. cycle through the container where the images are stored for scrolling
4. Attach everything to the container from point 2.
5. ???
