It was

.gallery .gallery-caption {
	display:none;
}

in the style.css .

You helped be accidental by talking about “caption”.
I needed to add

.gallery .gallery-caption {
	display:none;
}

I was looking for “alt” all the time.

Thank you ??

Oh, I was wrong there, it’s not the alt attribute. Thank you.
Anyway, there’s an image description which is shown under the images. I want to hide it on normal pages, but not delete it because I wanna see it on attachment sites, galleries, …
I hope it’s clear now what i’m searching for.

Thanks.

As I dont know much about php, I am still unable to implement the following code.

<script>(function(d, s, id) {
  var js, fjs = d.getElementsByTagName(s)[0];
  if (d.getElementById(id)) return;
  js = d.createElement(s); js.id = id;
  js.src = "//connect.facebook.net/de_DE/all.js#xfbml=1";
  fjs.parentNode.insertBefore(js, fjs);
}(document, 'script', 'facebook-jssdk'));</script>

<div class="fb-like"  data-href="#" data-send="false" data-width="300" data-show-faces="false" data-font="arial"></div>
<hr>

Can you tell me where to insert these lines?
