A few new images were approved, but has Alamy implemented a new system?

In the past, when an image was approved, there was no comma to separate the keywords. This time, there are.

What happens? Do I delete the commas or leave them there?

Leave them if they are separating keywords or keywords phrases and check out their forum

Thanks, Sue!

I don't visit Alamy forum. Were there discussions about this matter?

If commas are required between the keywords, what about our old images? Do we need to edit them or will Alamy implement the change?
