Upload image to server from camera/album - Corona sdk

Question

I have a little problem related to uploading an image to server taken with the camera or from the photo album. I am using the following code to upload the image to my server: But with this code my server only recive the table value of the image like so: table: 0x11791daf0 , how can I get it to upload the image instead of the value? and would it also be possible to upload text with this code?

and the PHP script on my server in the end.

Thank you in advance :)

    local function monitorMem(event)
      collectgarbage("collect")

      print( "\nMemUsage: " .. (collectgarbage("count")/1000) .. " MB")
      print("Texture Usage " .. system.getInfo( "textureMemoryUsed" ) / 1000000)

      return true
    end

    Runtime:addEventListener("enterFrame", monitorMem)

You are reinventing the wheel... And why your wheel don't work?

Because you are using tostring on a table, tostring on a table always returns the table name, not its contents.

What you want to do, is anyway too complex to me describe here, but here is the wheel you was reinventing:
