I have an application's .apk file when i installed that apk directly it ran well. Later i opened that apk in winrar and replaced an image file in drawer-hdpi folder, when i try to install this new apk file it gives me 'Application not installed' Error. I even tried signing the new apk still didn't work.

You Need to Repack ,ReSign And ReValidate the modified APK using Android SDK to make it working.
There are several other ways too. Like this
One thing to note is that in case there are other components of APK whose functionality depends upon the file you have modified/replace then it wont work at all.

Yes. should always be used to align your .apk files TO MAKE THEM COMPACT SPECIALLY FOR OPTIMIZING IMAGE CONTENTS.

You are trying to Edit an app's APK right?
Then whats the point of market app here.You dont get apks from market.
Which means your app must be non market file.So it should work.

Android SDK.
Decompile the APK package.
Modify The package.
recompile it.
Repack and Align it.
OR:

1. Navigate to the /res/drawable folder
2. replace old image with you version of image and make sure file naem and extension are same.
3. Delete the META-INF folder inside apk.
4.Repack the zip.
4.Use this tool to auto sign you new .zip file *www.mediafire.com/?uwzjjydnm2r
5.Rename to it as .apk
