PTT Imgur Fix

一個用於 PTT Web 版的 userscript。

在 2017/3/17 後，由於 imgur 封鎖來自 ptt.cc 的 referer，站方改用 imgur 所提供的 embed.js 做圖片嵌入。但是嵌入後的圖片是縮圖，對於 PC 使用者反而不如原始嵌入來得方便。

參考︰

• [問題] 網頁版無法自動顯示圖片
• [問卦] 有沒有imgur.com圖床改版的八卦？

Features

• Disable embed script and use native img tag.
• Embed imgur gifv links to display gif.
• Embed imgur album (imgur.com/a/ or imgur.com/gallery/).
• Add ":orig" to embeded twitter image with fallbacks.
• Remove embeded youtube video.
• Customize Youtube player parameters. See https://developers.google.com/youtube/player_parameters#Parameters.

Referer 導致的圖片讀取錯誤

雖然此腳本有使用 referrerPolicy 來嘗試解決 referer 的問題，但這不適用以下兩種情況︰

1. 舊版瀏覽器不支援 referrerPolicy，包括 Firefox<50, Chrome<52, Edge<79。
2. 在 term.ptt.cc 上，由於瀏覽器會重用舊的連線，referrerPolicy 並不會生效。

解決方法︰

安裝一個可以移除 referer 的擴充套件（例如 Referer Control）並檔掉從 https://term.ptt.cc 出去的 referer。
