L204 & L205 - this is way back v21 in Lover path. Go back to the scene when Liz said "The weather is nice". Do not ask her to go to the park, just agree about the weather. By night, Liz takes a bath and will give you L204. Reply with a smirk emoji (😏) and ask for more pic to get L205.
L371 & L375 - you must do a High Will NTRS run. In the previous versions, you must get upset when Liz is taking too long in the bathroom, then decline sex, and then select the NTRS choices. Run the game until you reach the conversation with Liz before she boards the train to go to the outerbranch. Make a save1 then ask her to wear lewd outfit to get L371. After obtaining the pic, make a save2 then load save1 again, but this time do not ask to wear lewd outfit and you will get L375.
S46 - this is a developer's mistake because the pic is for the Lovers route, but there is no Lover storyline in v22. We have to wait for v23 that has the new Lover storyline to unlock that pic.
S61 - Happy normal path (not NTRS). You need to go to the outerbranch but get your own hotel room. Run the game until Sam arrives, too. During discussion she will ask if you can let her stay with you. You have to refuse to get S61.
E42 - Happy NTRS path. Before Liz boards the train, ask her to wear lewd. Continue until she masturbates in the train bathroom. After that, she will ask if you like it. You have to select "perfect" to unlock E42 posted in the Exhibitionist ShareSpace. Selecting "moar lewd" will give you E43-E47 instead.
