[solved] how to target every third picture with phx:math ?

Hi everybody,

i try to apply an extra class to every third picture of a gallery
right now i’m experimenting with the following:

this prints "margin" to the second picture, and from there on to every third.
How can i get it to start on the third picture?
[+maxigallery.picpagenumber+] starts counting from 1

...or is there a better/other way to accomplish this?

thanks, j

Did you try:

hey etal,

thanks - that worked
