Reset custom splash and header images

Hi All,

How do I reset these!?!

I created custom \codebase\wtcore\images\bblks\l_ptc_splash.gif and \codebase\netmarkets\images\22A_windchill_logo_x20.png files and replaced the OOTB ones.

Now, I've copied the OOTB ones back and they are not showing, e.g. my custom ones show inthe web browser even though the files are changed.

I have; 1. deleted the \instances 2. restarted everything 3. Cleared webbrowser cache

It must be caching these somewhere I'm missing. Any idea?

Thanks!
