I want to generate a table of images, something like:

So I’ve to put a   
 after 3 iterations, how should I do this?

I could make a counter initialize it on zero, increment its value and  
check it for “mod3=0”, but I think there might be a better way to do it  
in ruby?

I’ve something like:

\<% @games.each do |game| %\>

```
<%= link_to image_tag(game.image.url), game %>

```

\<% end %\>

Regards,  
Joris

Couple of options… you could do each\_with\_index and then print a  
  
 if i % 3 == 0. You might not get a   
 on the last line though.

Or you could use in\_groups\_of which is meant for this sort of thing.
