Photoshop script that exports to PNG all layers and groups whose names end with ".png".

Hi Tom,

It tried this script but it crashes photoshop and creates an empty out folder. Any chance you can have a look at it when you're free...it would be really helpful.

Thanks

Jay

@jaysuthar Script works fine (CS6) just make sure you label your layers with a .png ending:
e.g. "Home.png" "banner.png" or it will ignore it.

@tomekc really helpful script, thank you
