If the dev did it, some people would complain about how he/she organized it. So.....
Make Your Own Galleries
(NOTE: Everything below is how I do it for my Windows 10 computer. If you have a different OS, you may have to use different methods).
1. Download one of the .RPA file extractor utility programs, like RPAExtractor or UnRen. Then you can easily extract ALL the Pictures (normally JPG's) and Videos (webm files) to a new folder somewhere. Just follow the directions included for whichever utility program you use to extract the files. It's REALLY EASY to do.
2. Create your own separate "graphics" storage folder(s) somewhere for the game's Pictures ("renders") and Videos ("scenes"). How you organize this is up to you. You can see how I did it in the screencap from my computer below. I have separate main folders for each game I play, then sub-folders for the Pics and Vids by character name. Note that in my "Vids by Character" folders I have also used the "Take a Snapshot" using VLC Media Player (see #3 below) of each webm scene and named it the same as the webm video filename. When you list the files then by "Name" you have a "snapshot" of what the actual "scene" is right in front of the scene file (NOTE: Where there is only ONE "screencap" in front of TWO or more webm "scenes", it is because BOTH scenes are the same...they are just different SPEEDS of the scene the Dev included). And because the Dev names the webm "scene" files by the Character Name and the WEEK they are in the game, everything stays in a nice order if your file list is sorted "By Name" (in some games where the dev doesn't do that, I'll just rename the saved files myself so I know "where they happened in the game", etc).
3. Use a free video player that will play webm files to play the "scenes" anytime you want without ever having to start the game itself. I use VLC Media Player (free open source player). You can even speed up/slow down the webm files when they are playing, plus tons of other "effects" for them too with VLC Media Player. Wanna spend 30 minutes watching the MC do Melody in the same scene? Have VLC "Loop" play the scene. In slow motion? Adjust the speed playback in VLC (Note this ability also solves the problem if you think previous version "scenes" play too fast or slow or whatever...you can now play any scene at any speed you want to watch it). With various "effects" you can make VLC apply to the playback? Black and White? Mirrored? Tons of others? Knock your rocks off.
As you'll see in the attached picture below of my hard drive list where I do this for ALL the games I have, I also save many (but not all) of the game's Pictures in separate "Pics by Character" folders too. I can then use a "photo gallery" program (I use the ACDSee payware one, but there are plenty of free ones too, even in Windows itself) that can run a slideshow of the entire photo collection (or selected parts of it, like just my Melody character pics, etc) if/when I want to just "Look at the pretty renders!" without having to run the game and "hunt" for them.
SPOILER CAUTION: If you enlarge the below thumbnail, you will see Screencaps of ALL of the Melody Week 10 videos (webm files) I added to the folder containing all the previous week's (1 - 9) scenes. If you looked in the other Character folders in the list on the left side, I have ALL the scenes for those characters in those folders too. When the Dev releases a new version of the game, I just add the NEW pictures and videos to my existing folders after extracting them from the NEW version. In each "Vids by Character" folder, I have ALL of that character's video "scenes" from the entire game. So I have created my own "scene gallery" exactly the way I want it, without putting that responsibility on the Developer. If all you wanted was PICTURES of what was in the scenes, you could even delete the actual webm files and just keep the "snapshots" of them.
