How to make a GTK window scrollable? - c

Question

I'm developing a program using GTK3, glade and C language, but in one of the windows i need to make only part of it scrollable (the size of the total scrollable area won't change), but i'm having a hard time with it.

This is the code i've written so far, i want to keep it as simple as possible cause i'm working with people who don't know GTK.
The current widgets added in glade
The current design of the window
The thing is that i want to put images there, make one side (left of scrollbar) scrollable and displaying the photos and the other side immobile.
I'm new to programming, so i'd appreciate if you could explain it in a simple way.
