What version of the product are you using? On what operating system?

local image_avail= iup.GetAttribute(clipboard, "IMAGEAVAILABLE")
print("image_avail",image_avail)
if image_avail == "YES" then
    local nimage= iup.GetAttribute(clipboard, "NATIVEIMAGE")
    print("nimage",nimage)
    local clipboard_image= iup.GetNativeHandleImage(nimage)
    print("clipboard_image",clipboard_image)

This project is just a combination of the modules that make up a distrobution 
of Lua. We don't develop the modules here. Please post this to the Lua Mailing 
list (http://www.lua.org/lua-l.html) for further help.
