Image size changing


When I have an javascript with:
IR.GetItem("Page 1").GetItem("Button").GetState(0).Image = "pict.jpg"; 
It ads an image to the button.
When I ad:
IR.GetItem("Page 1").GetItem("Button").Width = 500;
IR.GetItem("Page 1").GetItem("Button").Height = 100;
It changes the button size, but not the image size.
How can I change the image size in the javascript? 

You can not change image size with script, but you can change image size with item property "image stetch" = propoptional (or full size).  if property image stetch = prooportional (or full size) then image auto change size after set.
how change property image stretch? select item, open object properties panel, select tab states and find this property.
