I'm new to Illustrator. I downloaded a stock image of a bubble popping from Adobe (link), but I need it in a sprite png format with transparency. When I open it in Illustrator, there appears to be 1 artboard with a bunch of layers on it:
The first row is in one group, and the second row is in another group. And then there are sub-layers, with "paths", for the boxes and numbers. Is this a common layout? How can I convert this into a sprite png?
