This code sucks, but it works. I made it quick because I saw that no one answered your question .. About the Google API, you will make some requests and you will have some errors, this API is paid, the API you sent above is obsolete, it is now the Custom Search that is in use. So if after a few tries you can not do it might be due to this charge.
Code:
<html>
<head>
<script src="http://code.jquery.com/jquery-1.11.1.min.js"></script></head><body><script>//UsandojQuerya=$.getJSON("http://ajax.googleapis.com/ajax/services/search/images?v=2.0&hl=pt-br&cr=countryBR&q=carros")
.done(function( json ) {
b = jQuery.parseJSON(a.responseText)
for ( var i = 0; i < b.responseData.results.length; i++ ) {
document.write("<img src='"+b.responseData.results[i].unescapedUrl+"' />");
}
})
.fail(function( jqxhr, textStatus, error ) {
document.write("Erro ao capturar JSON");
});
</script>
</body>
</html>
