Google search by image from own webpage

Question

Is it possible to search by an image directly from my own webpage?

i will like to insert an url like: "http://thegalaxyguide.com/galaxy/sun/ultra_violet_sun.gif" and then be redirected to google and watch the result.

i tried this

    <form method="get" action="http://images.google.com/searchbyimage"
    <input type="text" />
    <input type="submit" value="Search" />
    </form>

but it is just going to googles own "search by image" page...

Answer 1

This does

<form method=get action='http://www.google.co.in/searchbyimage'>
<input type=text name=image_url value='https://www.google.com/intl/en_com/images/srpr/logo3w.png'>
<input type=hidden name='encoded_image' value='' />
<input type=hidden name='image_content' value='' />
