Deoptimize iPhone PNG's to view thumbnail or similiar

I was curious if there is anyway to deoptimize iPhone pngs using WinSCP? Maybe a plugin or a script?

All I need is a quick preview to verify what the png icon is without jumping through hoops and hacks to convert one.

Currently I'm using iPhoneFixPng.exe and it's aggravating transfering files over to a folder, running the 3rd party app to convert, and then opening the 'Fixed folder' to view the fixed pngs, just to get a preview of the icon.

I tried iFunbox and it previews the png icons, but I prefer to use WinSCP.


Thanks

I assume this is not possible??
