Icon backdrop on Samsung Galaxy S? how to change this?

I see a backdrop being added to my launch icon on the Samsung Galaxy S devices. I need this backdrop changed to a custom backdrop which we created. I know this can be changed since apps like"Daily Briefing" have their own cloud like backdrop making the launch icon look really rich. If anyone does know how to change this backdrop please let me know.

Take a look at the Icon for DAILY BRIEFING. You can notice the cloud backdrop for DAILY BRIEFING. I would like to control the Icon backdrop and if possible the size of the Ico开发者_Python百科n Eg. See difference between the size of GOOD and YAHOOMAIL

Thanks in advance. Appreciate your help.

The backdrop is Samsung specific. If there is a way to remove it, I would check on Samsung's developer site or ask them. From the apps I've worked on, I have not seen a way to change it.
