Save As PNG script

The following script retains the original colour space and embeds the same ICC colour profile into the PNG, while saving to a subdirectory of the input folder named PNG:

I was wondering if there is a way to save the PNG into a SubFolder of the InputFolder named 'PNG'

So I found this way around. It wokrs but you need to set Photoshop to preserve the embedded color profile.

                    function colorProfileType() {
                        app.activeDocument.colorProfileType = ColorProfile.custom;
                    }

I just hacked a script that I previously hacked from another script... Hope it helps (there is both a save for web and save as version):

In the save as version, I found very large file sizes using pngOptions.compression = 0

Any value from 1 - 9 was preferrable
