How To Convert PNG to PSD Batch And Script Photoshop Plugin

You said this code was how to make an increasing number then save the file then increase the number then save the file etc. but how can you change it for PNG-24 instead of tiff. I want to do this for a bunch of YouTube thumbnails but I am having to do it manually and it is frustrating as I need about 300. Please email finished code to mrdons2004@live.co.uk

Thanks
