title: Which free image resizing library can I use for resizing and probably serving images?
body: <p>I have used Umbraco and there is very nice ImageGen library there which allows to resize images 'on the fly' and cashes processed images.</p>
  
  <p>Is there something similar to it I can use outside Umbraco?</p>
  
  <p>(I thought I could use ImageGen without Umbraco but it looks like it is not free)</p>
  
  <p>Thanks</p>
