I've done this years ago in another program..(obsolete). I'm trying to create a png file for a webpage that has a picture logo on one side of a rectangle shape that is transparent . I can create the rectangle shape, and I can add the picture but its on a layer below and is covered up by the rectangle shape . I've been reading here and in the help files both online and local and I've tried to routine in the training video to no avail. I know this is something simple that I'm missing and hate to bother people with my dumb question. But I have tried to find the answer on my own...
So I guess I'm asking how do I make a shape I create become transparent and paste another picture/logo onto the rectangle shape?

Thanks for looking and the help.
