That's what it's there for so go ahead and use it.

Good luck with your game!

Gallery shouldn't be too hard if you make a simple one with imagebuttons and the example mentioned above.

https://www.renpy.org/doc/html/style_properties.html

idle - the image for when an item appears on screen but isn't hovered or clicked.

hover - when the image is hovered over with the mouse and clicked.

insensitive - it's disabled for whatever reason.

imagebutton auto "gui/gallery/h-scene01_%s.png" action Replay("Ll", scope={"player_name": persistent.player_name or "Jacob"})

the "auto" part fills in the "%s" with one of those states so have images called:

h-scene01_idle.png

h-scene01_hover.png

h-scene01_insensitive.png

Having three helps the player know they can interact with it yet you can get around with only idle and hover if you make a generic locked image though you might want to do that without using auto.  Replay by default will report if the scene can be replayed if the player has seen the label but if they haven't it switches to insensitive.  Insensitive can be used to give hints about the scene.

For a bit more finesse you could even include tooltips
