This is my preset to Save PNG as transparent ( with no black lines) 
around the tube or tag  & optimized it ( shrink make smaller ) for the web . 
This are the setting I have always used  hope it helps. 

Directions :
To Save your  File as PNG and Optimize it for the web.
You Must use Save As option for the Optimize area to open & to show. 
1:-Pick File/ Save As 
The Regular Save  & Save Copy As options does not have the optimize option and area .    


This goes in your Paint Shop Pro Folders  in The Document AREA in the Preset Folders I usually put them in 
Document PSP Folders  instead of the Main  Program Folders .. Because of upgrade and maybe loosing it ..


Location:

Put  them here and backup folders if you ever do a upgrade or uninstall -reinstall of PSP
