A representation of an image.
Only images up to 30MB in size are supported.
This message has oneof_ fields (mutually exclusive fields).
For each oneof, at most one member field can be set at the same time.
Setting any member of the oneof automatically clears all other
Image content represented as a stream of bytes. Note: As
with all bytes fields, protobuffers use a pure binary
representation, whereas JSON representations use base64.
This field is a member of oneof_ data.
