In order to realize the still image transmission method, input and store the chain data associated with the still image transmission device of the transmission destination in advance to each still image transmission device and store it as its own transmission destination in the chain data. A main still image transmission device for sequentially transmitting the encoded data and the chained data to an associated still image transmission device; and receiving and storing still image encoded data and chained data;
When there is a still image transmission device associated as its own transmission destination in the chained data, a slave still image transmission device that transmits the encoded data and the chained data to the still image transmission device is provided. A still image transmission system, characterized in that: 【請求項３】 １番目の主静止画伝送装置から２〜１６
