Phone How to sign an apk

HI!

I have a problem with an apk i am trying to edit. So i have an apk that i changed from .apk to .zip and then opened it with WINRAR to replace original PNGs with new PNGs becouse i didnt like them haha (i kept the same name). then i changed extension back from .zip to .apk and when i tried to install it on my phone (Xperia Miro ICS) it gave me an error. Please help me, what can I do?

except system apk, you must sign it. Using apk editor is easier if you only change .png.
