So I've been asked to make to make a small tutorial for my custom renpy gallery, well it looks like a lot, but it's actually quite simple, so don't let the size of the post discourage you, a lot of the code is probably not even necessary for most of you since I've included a gender choice option that is entirely optional 
The gallery itself is relatively simple, it's actually somewhat similar to the original renpy
One of it's main features is that you won't have to setup several pages once you add more content, you only set the grid size and the script does the rest.
Also once setup, you only need to add the image/scene names for every image/scene you want to show up in the gallery and nothing else. You can basically add an unlimited amount of images/scenes without any extra coding.
For this tutorial I expect you to at least have some basic renpy coding knowledge, I won't explain how to set up an imagebutton or something similar!
So lets start.
First thing we need is the function that determines if an image has been seen already:
This returns the image name if it has been seen in game, otherwise it will return a placeholder image (nope.jpg).
If you want to add another screen for scenes for example you can copy the code above and only have to change ID names:
Next up is the list of images that you want in the gallery:
In case of scenes you want to add the scene name, but also an image that represents the scene:
Note that in this case the image comes first, then the name of the scene!
Next we declare a few variables and images:
We want the player to be able to end a replay, so we need to make an exit button:
I use different screens for images, scenes and also a "special images" gallery that is hidden until the player finishes the game, so I use another screen to choose which gallery the player wants to see:
In my game you can chose the gender of the mc and because of the way I implemented it in the game I had to make an extra option to chose the gender for scenes here as well (ignore this if you don't need it):
You'll obviously have to set the persistent variables in the game for it to function. Of course you don't need this if you don't have a gender choice in the game.
Now to the actual gallery:
The scene gallery is basically the same, just that I had to add a condition for gender specific scenes, this is of course only necessary if you have a gender option:
If you don't have a gender choice delete the second if part and only leave the else part (without the else of course). Don't delete the second else!
Important is that you have a persistent variable for the mc name.
Now to the part where we display the actual image:
This simply displays the image, nothing special here.
Once the game grows, so will the gallery, this means we have more images then we can fit on one screen, so we want to be able to change pages:
I'm using two images with arrows to indicate the page direction change, both images are 316x1080px (for a 1080p screen). For some reason I saved them in the gui folder instead of the images folder like all the others, no idea why, so keep that in mind when you save your images.
Lastly you've probably noticed that I used some custom styles, so we have to create them as well:
My gallery styling is very simplistic, so this is the part where you can edit most of the styling.
And that's it, you can copy most of the code and only change the image names (or name your images the same) for buttons and of course the persistent variable names and it should work out of the box, just remember that some of the code is for a gender choice and edit it when necessary (make sure to read the comments in the code as well).
As I said, my design is very simple, but you can change almost everything to your liking:
There's probably room for improvements! I'm far from being a pro, so I invite everyone with a bit coding experience to give feedback and suggestions.

in a way, but much more customizeable and not as restricted.One of it's main features is that you won't have to setup several pages once you add more content, you only set the grid size and the script does the rest.

So lets start.
First thing we need is the function that determines if an image has been seen already:
Python:
init python:
def galeryImg(imgID):
if renpy.seen_image(imgID):
return imgID
else:
return "nope.jpg"If you want to add another screen for scenes for example you can copy the code above and only have to change ID names:
Python:
def galeryImgscene(imgIDscene):
if renpy.seen_image(imgIDscene):
return imgIDscene
else:
return "nope.jpg"
Python:
define nameByID = ["my image one",
"my image two",
"some other image",
"yet another image"
]
Python:
define nameByIDscene = [["my image one","my scene one"],
["my image two","my scene two"]
]Next we declare a few variables and images:
Python:
default gridSize = 9 #The gallery is a grid of 3 by 3 images, so this has to be 9, if you want to change the grid size you'll have to change the "grid" value and the gridSize value accordingly.
default page = 0 #The default value for the page the user is on. If there are more than 9(gridsize) images this scipt will automatically add more pages
default pageImageCount ="" #A placeholder variable, more on that later
#placeholder image
image my_image:
"nope.jpg" with dissolve
Python:
screen endRep():
zorder 666
imagebutton auto "exit_%s.png" action EndReplay() yalign .99 xalign .99
Python:
#main gallery menu
screen gallery():
style_prefix "galleryint"
tag menu
add "mm_anim" at zoomEffect #I use the background of the main menu here "mm_anim", this could be changed to a simple image or whatever you want to show in the background
vbox:
textbutton "Scenes" action ShowMenu("g_scenes")
textbutton "Images" action ShowMenu("g_images")
if persistent.gallery_special: #This is the special gallery as mentioned above, delete this and the line below if you don't use something like that
textbutton "Special" action ShowMenu("g_special")
textbutton "Return" action Return() xalign 0.5 yalign .99 text_outlines [ (0, "#333", 2, 2) ]
Python:
screen g_scene_gender(curr_scene):
modal True
style_prefix "choice"
vbox:
textbutton _("Male") action [ Hide("g_scene_gender"), Replay(curr_scene, scope={"pc_name":persistent.pc_mname, "pcthink_name":persistent.pc_mname, "pcgender":"man", "pcmd":persistent.pcmdm}) ]
textbutton _("Female") action [ Hide("g_scene_gender"), Replay(curr_scene, scope={"pc_name":persistent.pc_fname, "pcthink_name":persistent.pc_fname, "pcgender":"woman", "pcmd":persistent.pcmdf}) ]
textbutton _("Cancel") action Hide("g_scene_gender")Now to the actual gallery:
Python:
screen g_images():
style_prefix "gallery"
tag menu
add "mm_anim" at zoomEffect #Again the main menu background
default page = 0
grid 3 3: #Change this value if you want to change the grid size, make sure to change the gridSize variable accordingly
for i in range(page*gridSize,(page+1)*gridSize):
if i < len(nameByID):

$ pageImageCount = nameByIDscene
use changePagesImportant is that you have a persistent variable for the mc name.
Now to the part where we display the actual image:
Python:

add my_image xalign 0.5 yalign 0.5
textbutton "Return" action [ Hide("g_image_full") ] xalign 0.5 yalign .99 text_outlines [ (0, "#333", 2, 2) ]Once the game grows, so will the gallery, this means we have more images then we can fit on one screen, so we want to be able to change pages:
Python:
screen changePages:
if len(pageImageCount) > (page+1)*gridSize:
imagebutton:
idle "gui/galery_right_idle.png"
hover "gui/galery_right.png"
action SetScreenVariable("page", page+1)

if page > 0:

style galleryint_button_text is button_text:
