> 1) accept command returns a connectionID. How and where is it returned?

Peter, It's returned with the message.
here's part of a script from my stack cross-platform file transfer utility
"Sendreiver" with source code located at:
http://www.altuit.com/webs/altuit2/RunRev/Sendreiver.htm

moreData is the message sent
s is the connectionID sent
m is the data sent

actually, it's a bit easier to just download the stack and look in the stack
script. Sorry it's not too pretty, but it is easy to read.

on moreData s,m
  global gDATA
  #doMsg m
  put m after gDATA
  if last line of gData = "</altend>" then
    #doMsg "got last line"
    delete last line of gData
    hide img "spin"
    set the repeatcount of img "spin" to 0

    put line 1 of gDATA into f1Name
    delete line 1 of gDATA

    put fld "default_folder" &"/"& f1Name into fName
    domsg "fName:" & fName

    put base64decode(gDATA) into gDATA

    open file fName for binary write
    write gDATA to file fName
    close file fName
    doMsg "File Transfered: " & f1Name

    closeConnection s

  else
    doMsg "still reading"
    read from socket s with message "moreData"

  end if

end moreData

As Sara points out, use "last image"

FWIW, I'm not too crazy about the image library. You'll need to copy the
images from the library to your stack before creating an executable (unless
you include the image library stack) and when you copy the images, they all
get new image ID's which screws up your icons on your buttons. I've found it
better to just copy the images I want to a blank card on my stack, then
reference them from there.

Perhaps I just don't 'get it'

best,

Chipp
