What

When an image fails to decode, Claude Code now checks for two specific cases and reports a tailored reason instead of a generic failure message:

  • a CMYK JPEG (a JPEG using a four-color printing color model instead of the usual RGB), reported as "it is a CMYK JPEG, which Claude Code cannot decode"
  • an animated WebP file, reported as "it is an animated WebP whose first frame Claude Code cannot decode"
Why

This makes it clear why a particular image failed to load, so a user can tell the problem is a specific unsupported format rather than a generic error, and can convert the image accordingly.
