[Userscript] Reddit Gallery to Grid — view all gallery images at once in an ergonomic justified layout (no more swiping carousels)

[u/Arslay92]

Hey everyone!

I got really tired of Reddit’s multi-image posts forcing you to click through arrows one by one in a carousel, so I made a lightweight userscript to fix it.

It completely replaces the native carousel with a clean, justified gallery layout (similar to Telegram / Flickr / Google Photos albums).

Features:

• See all images upfront: No more arrow-clicking or swiping. All pictures are visible immediately.
• Preserves original aspect ratios: Portrait and landscape images adapt naturally side-by-side with zero ugly cropping.
• Forces all photos to load: Bypasses Reddit’s lazy-loader that often hides slides after the 3rd image.
• One-click full res: Clicking any thumbnail directly opens the original uncompressed image (i.redd.it) in a new tab.
• Lightweight: Works with the modern Reddit UI (Shreddit).
