I am attempting to send a jpeg image file created on an embedded

what the file size is?
You don't. Sockets are just endless streams of bytes. You will have to design some form
of 'wire protocol' that includes the length of the message that is to be read.
For instance a minimalistic protocol could be the following:
Send 4 bytes that contain the length (an int) then the data itself. The client reads 4
bytes, decodes it into the integer that tells it the length, and then reads the correct
amount of bytes from the socket.
