title: Tumblr theme dev: Square-75px photos for Photoset posts
body: <p>I am trying to use Tumblr's Theme API and just found out that for <a href="https://www.tumblr.com/privacy/consent?redirect=https://www.tumblr.com/docs/en/custom_themes#photoset-posts" rel="nofollow noreferrer">Photoset posts</a>
  the variable <code>{PhotoURL-75sq}</code> (which should be inside <code>block:Photos</code> won't return a value.
  It works ok for single photo posts but not for Photosets.</p>
  <p>Also it seems that the picture itself gets generated but the API doesn't
  return a proper value for example:</p>
  <p><a href="https://i.stack.imgur.com/N7acx.jpg" rel="nofollow noreferrer"><img src="https://i.stack.imgur.com/N7acx.jpg" alt="" /></a><br />
  <sub>(source: <a href="http://28.media.tumblr.com/tumblr_lzvey54yzV1ro516ho2_250.jpg" rel="nofollow noreferrer">tumblr.com</a>)</sub></p>
  <p><a href="https://i.stack.imgur.com/pLwOo.jpg" rel="nofollow noreferrer"><img src="https://i.stack.imgur.com/pLwOo.jpg" alt="" /></a></p>
  <p>the images above where uploaded into a photoset post using tumblr control panel, and as you can see, by just replacing the end of the filename 250px image with <code>75sq</code> it shows up correctly (which means it was indeed generated).</p>

  <p>but when using `{PhotoURL-75sq}', it won't return it's value.</p>
  <pre><code>{block:Photoset}
      &lt;h1&gt;{TimeAgo}&lt;/h1&gt;
      &lt;div class='slideshow'&gt;
          {block:Photos}
              &lt;img src='{PhotoURL-75sq}' alt&gt;
          {/block:Photos}
      &lt;/div&gt;
  {/block:Photoset}
  </code></pre>
  <p>I am not sure if this is the right place to be asking for this but since their support refuses to help me by saying:</p>
  <blockquote>
  <p>Unfortunately, we can't provide technical support for HTML customizations. Given our large number of users, we just don't have the resources. Our apologies. If you'd like to learn more about HTML and CSS...</p>
  </blockquote>
  <p>Where in this case I am thinking that or this is a bug or they simply renamed that variable when it's inside a Photoset without letting the developers know about it.</p>
  <p>Thanks in advance</p>
