Ben, You can use the SAS option 'splashloc' to set the graphic. In windows you would put this in the RUN line located in the properties menu. (by right clicking) In the run line all SAS options are always preceded by the - sign.

ex. of run line "c:\program files\sas\sas.exe" -splashloc "c:\test\your_picture.bmp"

This will launch sas (assuming that the SAS exe file is at that location) with your picture. The only con to this method is that only bmp works easily.

Hope that this helps ya. Jack
