Maybe if you look at it from far away enough.

Watermarking tries to resist image data manipulation. Smuggling data is concerned with preservation of bytes.

Though if we're executing arbitrary code on the target anyway, ways of embedding data in an image are vast, including watermarking/steganography.

Steganography has rather obvious size limits if you want the image continue looking innocent. EXIF data is way less limited.
