I don't often look at 123RF these days given the low volume of sales.  But I did check my account balance today and was surprised to see a message that 123RF now accepts PNG files.

I couldn't find any explanation on the web site, and using search filters I couldn't see any options for selecting PNG unlike Adobe which has transparent backgrounds as an option.

Is this something new and early days for 123RF?  Does anyone have any experience of PNG files there?
