python - What's the maximum size of a image to send using MQTT -

-

i'm trying send images using mqtt in 2 r-pi. wonder what's maximum size of image send. think 1mb maximum size however, 26.5kb image not sended. please give answer of question thank you.

mqtt doc mosquito:

message_size_limit limit

this option sets maximum publish payload size broker allow. received messages exceed size not accepted broker. default value 0, means valid mqtt messages accepted. mqtt imposes maximum payload size of 268435455 bytes.
