Transparency in PNGs?

Hi,

I'm working on an AveTunes skin, but I'm stuck here...

I'm going for a reflection type thing underneath it, but I have no clue how to do this.

How do you get partial transparancy on a PNG? I'm trying to get something like this:

see how there's a partially transparent "reflection" below it? I'm trying to do something like that.

1) Copy the artwork to a new layer

2) Rotate the contents of the new layer 180 degrees

3) Lower the opacity of the new layer to make it semi transparent

4) Apply a gradient mask to the layer to get it to fade to nothing

5) Crop the image down to the size you require

6) Export as PNG - must be RGB/32bit (or use "Save for web" and select PNG-24 + transparency)

@gtn: For no. 2, it should be Flip Vericaly, rotating it 180 degrees wont work unless its symetrical.

Uh, yeah... whta carbonfiber said. (I don't know what I was thinking )

Thanks, guys.. it worked perfectly!
