Not yet but hopefully someday there will be. The developer might add a scene gallery themselves once the game is finished but I don't really know for sure.
Honestly, I'm wondering if they'll really make the full series trilogy like they originally planned... because all three together will likely take 15-20 years total so I'm kind of doubting it (unless they hire extra help). I hope they do however, especially since there's supposed to be potential consequences for some things in later games. In this game there's no real negative consequences for your actions beyond not getting to see a certain scene or whatever. (On that note, I like how you see different scenes depending on your choices though, like Michelle being sober, normally tipsy or blasted drunk will get you different scenes with the random dude at the bus stop for example.)
Because I'm not as focused on Lisa as other fans of this game, I can really appreciate how the dev has been adding more and more to older scenes and keeps building everything up and making it so any direction you go in will give you actually different results. You really have a lot of options to play with in this one and even some choices you think won't make a difference actually do.
