Perhaps, you know that google image search by local image file ..
But, Google does not Support API about only file search.
Just URL or Text search APIs are suppoted..
So i tryed to use URL like this : ( Text = stackoverflow )
https://www.google.co.kr/search?tbm=isch&hl=ko&source=hp&biw=1680&bih=922&q=image&gbv=2&oq=image&aq=f&aqi=g10&aql=&gs_l=img.3..0l10.2610l4751l0l4994l6l6l0l0l0l0l143l530l0j4l4l0.frgbld.#hl=ko&newwindow=1&gbv=2&tbm=isch&sa=1&q=stackoverflow&oq=stackoverflow&aq=f&aqi=g1g-S9&aql=&gs_l=img.3..0j0i24l9.36861l38876l0l39043l13l13l0l4l4l0l355l1319l0j6j0j1l7l0.frgbld.&pbx=1&bav=on.2,or.r_gc.r_pw.r_cp.r_qf.,cf.osb&fp=f4b31218673e39ba&biw=1680&bih=922

AMhZZ.... here is Code that Encorded from image file
But i can't make this Code from image file.
This is not just binary code to character.
This png file byte length is 187099
But Endcoded code length is not same that.
How can i make that code from image... ?????????

You already answered the question yourself..., though I'd like to change 'Support' to 'Allow'.
