General questions about #! hashbang urls and I use them correctly

Now I am writing a website that includes a fairly large gallery. On the first page of the gallery, the user displays a bunch of thumbnails with the URL: website.com/gallery.php

When they click the thumbnail, if javaScript is turned off, will it follow the url in href and go to the page called gallery.php? img = 67. If javaScript is enabled, the href click will not be executed, instead it will execute an ajax request to display a larger image and some text about it. URL changes to gallery.php #! Img = 67. The back button will return you to the thumbnails by pressing f5, a large image with text will be displayed. If someone copies the address using #! and sends it to someone, they will receive the same image (provided that the recipient has javaScript enabled).

My question is: did I correctly parse it so that Google would index individual gallery pages? Will Google index them twice, once using? Img = 67 and once C #! and if it is so bad? I use javaScript / Ajax to preload large images after loading a thumbnail page for speed. I have read a lot of negative reviews about the use of Hasbang azapines recently and am wondering if you can consider that this can be used here?

This means that the server requires additional work, as the server needs to support both versions (Ajax version and regular version), but I think it costs. These #! so ugly.
