 * Hi folks. With the function [`wp_get_attachment_image`](http://codex.wordpress.org/Function_Reference/wp_get_attachment_image)
   I can get an image-attachment as html img element. The element has a CSS class
   of ‘attachment-$size’ ($size is replaced by the argument you call the function
   with).
 * Now I want to add a CSS class to have something like <img class=”attachment-medium
   someclass”… />.
 * I thought this could be done with `wp_get_attachment_image( $attachment_id, $
   size, $icon, $attr=array('class' => 'someclass') )`…But this replaces the default
   class ‘attachment-$size’ with ‘someclass’.
 * It’s supposed to merge/append additional classes like [`the_post_thumbnail`](http://codex.wordpress.org/Function_Reference/the_post_thumbnail)
   does, isn’t it? So is this a bug or is it the intended behavior of `wp_get_attachment_image`?

   is the right forum for this question. If not, feel free to move it 🙂
