To set the contents of the embedded image, the client uses four ROPs.

The RopOpenStream ROP ([MS-OXCROPS] section 2.2.9.1) with the PidTagAttachDataBinary property (section 2.2.2.7).

The RopSetStreamSize ROP ([MS-OXCROPS] section 2.2.9.6) with the size of image file data.

The RopWriteStream ROP request ([MS-OXCROPS] section 2.2.9.3) with the actual file contents.

The RopRelease ROP ([MS-OXCROPS] section 2.2.15.3) for the handle returned from the RopOpenStream ROP.
