If you have multiple layers that need to be included, you'll need to go to the canvas settings panel and set the canvas opacity 0%, and turn the canvas light off, by clicking on the lightbulb icon. You can then export the image as a png file type, which will keep the transparency. If you just have a single layer with the sticker image, you can just right click on the layer it's on, and select the option to export the layer as a png.
If it helps at all, I have sticker tutorial posted here: http://www2.ambientdesign.com/forums...ad.php?t=30400

Nothing is easy to the unwilling.
