title: How to make same sized thumbnails
body: <p>I'm having a hard time now trying to make same sized thumbnails, 
  I have a simple gallery script that just takes all images out of database and places them to the page with max width 150px and max height 150px.</p>
  
  <p>Now , it looks weird because all images have different shape, is there any way to make them same size without breaking the image apart? The simplest way possible please.
  I don't want to have an option on uploading step to chose dimensions for thumbnail.</p>
