Change backgroound and Color and adding pic in to SAP GUI for HTML screen

Dear all,

I have ceated one SAP Transaction using SAP GUI for Windows and its working fine.

Now what I want to do now is that I want to change the look and feel of the page displayed for SAP Transaction.

For example, If I run a transaction say "pftc". I want to change the color of the page and do some more gui changes.

How is this possible?

Thanks,

Karan
