I don't believe PNG supports layers. You can take a multi-layer project and save it as a single layer PNG with transparency but you won't be able to take that saved file and open it like you would a psd or tiff file with the layers intact.

The native format for Fireworks (from Adobe) is "PNG" ... and yes, PNG has layers just like the Photoshop PSD format. Yes, the PNG format supports layers. And, those layers are present upon re-opening the file. But, you need a program that supports the layers. I believe Photoshop does import the PNG file made in Fireworks with the layers still intact...
Photoshop png files support working in layers while editing the file, but once it's saved as a png file (similar to saving as a jpg), the layers are collapsed and gone forever. They are simply not there any longer once the png file is reopened. At least this is the way it has been up to Photoshop CS 5.5 which is the version I'm using. If something has changed, then I stand corrected.
See the answer by the Adobe's own staff person in this thread in the Adobe Community forum website.
The PNG format does support layers as Fireworks demonstrates. However, as I said, most other applications (other than Fireworks) treat PNG files as flattened files. I was only pointing out that PNG supports layers (even if most other applications don't support layers in a PNG) despite assertions to the contrary...

Since you spoke of using Photoshop, I felt it prudent to stick to that tool and addressed the comment about png file layers being flattened when reopening a PNG file using Photoshop.
My comment was not related or pointed to Producer. But I'll address it now.
The issue about not being able to reopen a PNG file and seeing it's multiple layers again using Photoshop is different than whether PNG image files can be used in ProShow Producer. ProShow has supported the use of PNG (transparency) file format ever since I can remember and they can be placed in any number of slide layers. The term "layers" in Producer is a reference to slide layers of images, which is not quite the same as PNG image file layers in Photoshop. What is seen in ProShow is the flattened PNG image when used in a slide layer.
The initial problem was that the area needing to be transparent in the PNG file was not saved as transparent and is why the other slide layers were not visible in ProShow. Once the white area was replaced with transparency and saved as a PNG file as Osharr explained, other images under PNG slide layer in Producer are visible. Sounds like you have it figured out now.
Hope that makes sense.
