Files for iPhone: .ipa PNG

Question

How can I open PNG files from iPhone applications (.ipa)?

Example: I download the application in the iTunes App Store, click "Show in Search" to find the XXX.ipa file, rename it to XXX.zip, extract the files, open the directory, but I am not able to open PNG files. How can I open them?

Thanks in advance!

PNGs are crushed when entering .ipa files. You need to untie them.

Here are two tools to do this:

The QuickLook plugin PngUncrush.qlgenerator is found at: http://castelliweb.com/blog/2010/05/24/quicklook-plugins-for-mac/

or the iPhonePNG command line tool found at: http://www.newsfirex.com/blog/?p=176
