title: iPhone: .ipa PNG Files
body: <p>how can I open the PNG Files from iPhone Applications (.ipa)?</p>
  
  <p>An example: I download an App in iTunes App Store, click on "Show in finder" to find the XXX.ipa File, I rename it to XXX.zip, extract the files, open the directory, but I am not able to open the PNG files. How can I open them?</p>
  
  <p>Thanks in advance!</p>
