About This Extension

仅提供图片格式标注和含meta信息图片的下载功能,帮助你记忆图片提示词 提供图片格式标注与下载:当图片为 PNG/JPG 且页面可识别提示词时,会把提示词写入图片元数据(PNG iTXt / JPEG EXIF);其他格式将原样下载。仅适用于 imarena.ai,纯本地运行。 【功能】 在页面标题区域显示图片的分辨率与格式(如 PNG/JPG/WebP)。 点击“含提示词下载”时:若图片为 PNG 或 JPG,且能从页面识别到提示词,则将提示词写入图片元数据(PNG 使用 iTXt,JPEG 使用 EXIF 的 ImageDescription);若为 WebP/AVIF/GIF 等或无法识别提示词,则原样下载、不写入元数据。 【使用方式】 打开 LMArena 对话或结果页面,图片加载后即可在标题区域看到分辨率与格式标注。 当标注为 PNG/JPG 且已展示提示词时,点击“含提示词下载”保存图片(会尽力内嵌提示词);否则原样下载。 【重要说明】 本扩展仅适用于 imarena.ai 网站。 所有处理均在本地完成,不上传数据到服务器。 不改变原图格式,不进行格式转换。 能否写入提示词取决于页面是否可识别提示词,以及图片实际格式是否为 PNG/JPG。 ———— Show image resolution/format and download locally. If the image is PNG/JPG and a prompt is detectable on the page, the prompt is embedded into image metadata (PNG iTXt / JPEG EXIF). Other formats are downloaded as-is. Works only on lmarena.ai, runs locally. Features Display image resolution and format (e.g., PNG/JPG/WebP) in the header area. When clicking “含提示词下载”: if the image is PNG or JPG and the page shows a detectable prompt, the prompt is embedded into metadata (PNG iTXt / JPEG EXIF). For WebP/AVIF/GIF or when no prompt is detectable, the image is downloaded as-is without metadata injection. How to use Open an LMArena conversation or results page; once images load, the resolution/format appears in the header. When the label shows PNG/JPG and a prompt is visible/detectable, click “含提示词下载” to save with embedded prompt; otherwise it downloads as-is. Notes Only works on imarena.ai. All processing is local; no data is uploaded. No format conversion is performed. Prompt embedding is best-effort and only available for PNG/JPG when the prompt can be detected.
