url-title?

I have an event block that displays images.

I want to have 3 options: - if event has image, display that image - if event url title has a certain keyword, display that image - else display a placeholder image

I don’t know how to write the 2nd option to the existing code:

  {if event_photo}
    {exp:imgsizer:size src="{event_photo}” alt=”{title}” width=“300” height=“450” class=“displayBlock” quality=“100”}
  {if:else}
    /images/_pages/_global/placeholder.jpg
  {/if}
