Below I’ve got the following code working. it outputs the image and then the title of the parent entry via playa.
```
<article id="content">
 {exp:channel:entries channel="clients" limit="500" disable="member_data|pagination|comments|categories"}
  {client-logo}
  
  {exp:playa:parents channel="testimonial"}
   {title}
  {/exp:playa:parents}

 {/exp:channel:entries}
</article>
```
What I want to do is wrap the image tag abouve with a tags that return to the parent entries single page, but only if that relationship exists i.e.
```
<a href="/clients/testimonials/{url_title}">{client-logo}</a>
```
Not sure how to do that and would really appreciate advice.

Check the playa docs: http://pixelandtonic.com/playa/docs/templates and specifically scan for conditional variables.
There are quite a few available. You could for exanple use something like:
```
{if no_parents}
output image tag
{if:else}
output image tag wrapped with link to parent entry
{/if}
```

Erwin,

When I tried this:

{exp:channel:entries channel="clients" limit="500" disable="member_data|pagination|comments|categories"}
 {if count =="1"}<ul>{/if}
 <li>
  {exp:playa:parents channel="testimonial"}
  {if no_parents}
   {client-logo}
  {if:else}
   <a href="/clients/testimonials/{url_title}">{client-logo}</a>
  {/if}
  {/exp:playa:parents}
 </li>
 {if count == total_results}</ul>{/if}
{/exp:channel:entries}

It output an unordered list without any images inside, which is perplexing as it seems like it should work.

did you try parse=“inward” or dynamic=“no”?

update - I added another client this time without a relationship and now the template is giving me parse errors so I suspect there is something wrong with the conditional.

now using the following:
```
{exp:channel:entries channel="clients" limit="500" disable="member_data|pagination|comments|categories"}
 {if count =="1"}<ul>{/if}
 <li>
  {!--{client-logo}--}
  {exp:playa:parents channel="testimonial"}
  {if no_parents}
   {client-logo}
  {/if}
  {if parents}
   <a href="/clients/testimonials/{url_title}">{client-logo}</a>
  {/if}
  {/exp:playa:parents}
 </li>
 {if count == total_results}</ul>{/if}
{/exp:channel:entries}
```
Which outputs a list where the one entry that doesn’t have a relationship shows up an image tag but the custom field isn’t being output. Though if I use that custom field outide of the play tags it works just fine

Not sure if {if parents} will work. Which custom field from which channel isn’t being rendered?

Erwin,

The {client-logo} field isn’t rendering and it’s in the clients channel.

After some more experimentation I found the solution

{exp:channel:entries channel="clients" limit="500" orderby="title" sort="asc" disable="member_data|pagination|comments|categories"}
 {if count =="1"}<ul id="clients-logos">{/if}
 <li class="{switch="clear||"}">
  {if "{exp:playa:total_parents field="client-name"}"}
  {exp:playa:parents channel="testimonial"}
  
   <a href="/clients/testimonial/{url_title}">_  _  {/exp:playa:parents}{client-logo}</a>
  {if:else}
  {client-logo}
  {/if}
 </li>
 {if count == total_results}</ul>{/if}
{/exp:channel:entries}

Looks good, was going to suggest that everything inside the {playa} loop references the other channel but you’d already found it. Cheers!
