//*******************************************
// Script: Youtube Thumbnail Resize v1.0
//It does:
//  1.  Gets the youtube id.
//  2.  Gets the youtube thumbnail.
//  3.  Resizes the youtube thumbnail.
//  4.  Keep ratio.
//  5.  Make smaller source images bigger.
//  6.  Save the image to the given destination path.
//*
//It doesn't:
//  1.  Make directories.
//  2.  Crop.
//*******************************************

// Summary:
// This script is made to get the youtube thumbnail from the embed($src_embed so you
// can use it yourself. The image is saved with the width ($dst_w) and height ($dst_h)
// given by the user to the destination path ($dst_path) with the user provided name ($dst_img).

//Script start here.
