Answer 1

There are a couple of ways you could solve the “5 photos on a row” problem, but I think that this is the most expressive: group the array of photos into rows of 5 and use nested .each loops:

rows = @photos.in_groups_of(5)
rows.each do |row|
  <tr>
  row.each do |photo|
    <td>
    #display photo here
    </td>
  end
  </tr>
end

Be aware that if you don’t have 5 photos on your final row, array#in_groups_of will pad it with nil unless you specify an alternative default.
