Create a script to save multiple groups into seperate png files

Hello,

I want to use a script to save every group I made into a '.PNG. I'm visualizing something like this, but the outputformat/name doesn't matter, as long it is a output from a group:

group1 -> 1.png

group2 -> 2.png

group3 -> 3.png

group4 -> 4.png

etc.

I noticed that someone create a script like that, but it isn't using for me anymore. Find here the script that isnt working for me:

Re: Export Groups to Files?

I am using Photoshop CC 2014 on Windows 7 (64bit).

Looking forward to your reply! Thanks.

Kind regards,

Joost
