Maybe I use it wrong, but if someone can take a look.
I have code like this:
{exp:comment:entries sort="desc" limit="20" orderby="date" entry_id="{segment_2}"}
<div class='komentar'>
{if avatar}{avatar_url}{/if}
<a href="#" class='kom_username'>{name}</a><small> - {comment_date format="%d %m %Y"}</small>
{comment}
</div>
{/exp:comment:entries}
{exp:comment:form}
{if logged_out}
<div class='komentar'>
<a href="#" class='kom_username'>www.site.com</a>
some text
</div>
{/if}
{/exp:comment:form}
<div class='floatfresh'> </div>
</div>
</div>
{exp:comment:form}
{if logged_in}
<div id='dodaj_komentar' class='box box_vijest'>
<div class='box_naslov2'><span></span><h4>Add comment</h4><p><small></small></div><br />
<div class='vijest_slike'><br />
<div class='komentar'><br />
{if avatar}{avatar_url}{/if} <br />
<textarea class='kom_textarea' name="comment">{comment}</textarea><br />
<input value='Add comment' type='submit' class='kom_submit' name="submit" /><br />
</div><br />
<div class='floatfresh'> </div><br />
</div><br />
</div><br />
<div class='floatfresh'> </div><br />
{/if}<br />
{/exp:comment:form}in this part
{if logged_in}
<div id='dodaj_komentar' class='box box_vijest'>
<div class='box_naslov2'><span></span><h4>Add comment</h4><p><small></small></div><br />
<div class='vijest_slike'><br />
<div class='komentar'><br />
{if avatar}{avatar_url}{/if} <br />
<textarea class='kom_textarea' name="comment">{comment}</textarea><br />
<input value='Add comment' type='submit' class='kom_submit' name="submit" /><br />
</div><br />
<div class='floatfresh'> </div><br />
</div><br />
</div><br />
<div class='floatfresh'> </div><br />
{/if}avatar is not displayed. But on this part of code
{exp:comment:entries sort="desc" limit="20" orderby="date" entry_id="{segment_2}"}
<div class='komentar'>
{if avatar}{avatar_url}{/if}
<a href="#" class='kom_username'>{name}</a><small> - {comment_date format="%d %m %Y"}</small>
{comment}
</div>
{/exp:comment:entries}
it is displaying. How to fix that? Also, can I write this part of code in this way?
{if avatar}
{avatar_url}
{elseif}
There is no picture
{/if}
