Question about tutorial P2 to add picture

I am trying to add picture to my pluggo patch,
but every time I add the "C# infopict p2.pict;" to the end of the plugconfig script, the newly added script disappears after I save the script.

I also took a look at the tutorial patch P2, and I did not find "C# infopict p2.pict;" at the end of the script, either.

Could anyone tell me what is wrong ?

I would also like to know if jpg or bmp also works for pluggo info picture.

PS: I use Windows Pluggo and Max/MSP.

Thanks.
