❯ Original GitHub Copilot Prompts to download images

Write a script in Ruby that downloads all game screenshots from https://itch.io/jam/game-off-2025/results, which is a paginated results page.

Requirements:

• Crawl all pages of the results (follow pagination links until exhausted)
• For each game entry:
  • Extract the overall placement/rank (e.g. 1, 2, 3, 10, etc.)
  • Extract the game name as displayed on the page
  • Find the primary screenshot image shown for the game
• Download the image and save it locally using this filename format:
  <placement>-<game-name-lowercase-hyphenated>.<original_extension>

Examples filenames:

1-evaw.png
10-where-the-water-flows.gif
27-wave-length.jpeg

Filename rules:

• Convert the game name to lowercase
• Replace spaces and punctuation with single hyphens
• Strip non-alphanumeric characters except hyphens
• Preserve the original image extension (png, jpg, jpeg, gif)

Implementation details:

• Respect polite scraping practices:
  • Set a clear User-Agent
  • Add a small delay between page requests
• Create an output directory called screenshots/
• Skip downloads if the file already exists
• Print progress logs (page number, game name, filename)
• Handle missing images gracefully; skip 'em

❯ Original GitHub Copilot Prompts to create a montage wallpaper

Create a Ruby script that generates a wallpaper montage from game screenshots.

Requirements:

• Read all images from a screenshots directory (png, jpg, jpeg, gif, webp)
• Create a 3840×2160 pixel wallpaper
• Use ALL images - calculate the optimal tile size to fit every image
• Maintain the original aspect ratio (315:250) when scaling tiles
• Only repeat images if needed to fill the final row/column
• Output to wallpaper.png

Implementation details:

• Use ImageMagick (montage and convert commands)
• Calculate tile dimensions dynamically based on image count
• Center-crop the final montage to exact wallpaper dimensions
• Print progress info (image count, grid size, tile dimensions)
• Clean up temporary files after completion
