This extension embeds image generation metadata into the (unused) alpha channel of a PNG generated in stable-diffusion-webui.
Will not work for JPEG images. Untested on webp, should work in theory but who knows.
Please note that as this data is embedded in the image pixels, it is not visible in an EXIF data viewer.
It will show up in the PNG info tab in the webui and via bots like Prompt Inspector, but not via EXIF tools.
Extension auto-activates and runs alongside standard webui PNG info functions, no extra settings are required. It can optionally be disabled in settings if desired.
Forked from @ashen-sensored/sd_webui_stealth_pnginfo - this was originally created to get around Discord stripping the text sections from PNGs, but they've reversed that change so Ashen is not maintaining that anymore. I find it convenient though (since it doesn't rely on that data being retained, and many websites/devices will strip it) so here it is.
