title: Resize image after upload
body: <p>I want images to resize after upload in 4 different formats. If i resize it to best fit(i.e aspect ratio) some images come too small if height or width is too large than the other and if i resize it to  fixed size then images get skewed. So what is the best way to resize a image. I am currently doing this using via imagemagik <a href="http://www.php.net/manual/en/function.imagick-thumbnailimage.php" rel="nofollow">thumbnailImage()</a> but i think it's a general problem. What are sites like google or facebook doing. what is the best thing to do in that case</p>
