title: Using Amazon MapReduce/Hadoop for Image Processing
body: <p>I have a project that requires me to process a lot (1000-10000) of big (100MB to 500MB) images.  The processing I am doing can be done via Imagemagick, but I was hoping to actually do this processing on Amazon's Elastic MapReduce platform (which I believe runs using Hadoop).</p>
  
  <p>Of all of the examples I have found, they all deal with text-based inputs (I have found that Word Count sample a billion times).  I cannot find anything about this kind of work with Hadoop: starting with a set of files, performing the same action to each of the files, and then writing out the new file's output as it's own file.</p>
  
  <p>I am pretty sure this can be done with this platform, and should be able to be done using Bash; I don't think I need to go to the trouble of creating a whole Java app or something, but I could be wrong.</p>
  
  <p>I'm not asking for someone to hand me code, but if anyone has sample code or links to tutorials dealing with similar issues, it would be much appreciated...</p>
