How to change the icon and org name in Task Sequence

Hi All

I am new to SCCM, just started working on SCCM2007. I would like to know if there is a way to change the icon and Org name of a Task Sequence 

I did go through the similar thread, but i understand that is for a MDT integrated setup. I dont have MDT installed but i can do that if there so other way to do the above.

Please suggest.

Thank you

Regards Ram
