Some days ago I wondered how to embed an image's original URL into its meta data, and phancap now uses the same idea to add information about the screenshotted page, and the configuration used to achieve the website screenshot:
$ exiftool -S -G cweiske.de-bd30f41492ae162d922800b41210629c.png |grep XMP [XMP] Creator: phancap [XMP] Description: Capture options: browser window: 1024x0, screenshot size: 1024x0, format: png, mode: full page height [XMP] Subject: http://cweiske.de [XMP] Title: Screenshot of http://cweiske.de [XMP] Source: http://phancap.cweiske.de/imgcache/cweiske.de-bd30f41492ae162d922800b41210629c.png
- Human-readable list of options that were used to generate the screenshot. With that the screenshot can be reproduced.
- URL of the website that was captured
- "Screenshot of " + URL
- URL under which the screenshot was originally stored
