Drag-and-drop, Ctrl+V, re-host remote URLs to PixHost (auto-converts WebP/AVIF to PNG)
Adds a floating panel to pixhost.to that uploads images via drag-and-drop, Ctrl+V paste, or by pasting remote URLs (one per line, [img]...[/img] BBCode tolerated).
Remote sources that return WebP/AVIF/BMP are auto-decoded in-browser and re-encoded as PNG before upload, since PixHost only accepts PNG/JPEG/GIF.
Results are displayed as plain URLs, with one-click copy buttons for plain URL, BBCode, and Markdown formats.
Verbose [PixHost+] console logging at every network boundary for easy debugging.
为 pixhost.to 添加一个浮动面板（网页右上角），支持通过拖放、Ctrl+V 粘贴，或粘贴远程 URL（每行一个，可识别 [img]...[/img] BBCode 标记）来上传图片。
对于返回 WebP/AVIF/BMP 格式的远程来源，会在浏览器中自动解码，并在上传前重新编码为 PNG 格式，因为 PixHost 仅接受 PNG/JPEG/GIF。
上传结果以纯文本 URL 形式展示，并配有一键复制按钮，可复制为纯文本 URL、BBCode 和 Markdown 三种格式。
会向控制台输出详细的调试日志，方便排查问题。
