Avatar in text area

Hello,
I'm trying to drop the member's avatar image into the post entry textarea.
(in .../components/com_easysocial/themes/wireframe/story/default.php)

I did this:

<div class = "es-story-textbox mentions-textfield" data-story-textbox>



<! - ***** ->

<div style = "margin-bottom: 5px"> <!-- with border-radius:50% -->

<img src = "<? php echo $ user-> getAvatar (small)?>" />

</ Div>

<! - ***** ->



<div class = "mentions">

<div data-mentions-overlay data-default = "<? php echo $ this-> html ('string.escape', $ story-> overlay);?>"> <? php echo $ story-> overlay; ?> </ Div>

<textarea class = "es-story-textfield" name = "content" data-story-textField data-mentions-textarea

data-default = "<? php echo $ this-> html ('string.escape', $ story-> content);?>"

data-initial = "<? php echo ($ story-> overlay)? JString :: strlen ($ story-> overlay): '0';?>"

placeholder = "<? php echo $ nameUser; echo", ";?> <? php echo JText :: _ ('COM_EASYSOCIAL_STORY_PLACEHOLDER');?>"> <? php echo $ story-> content; ?> </ Textarea>



</ Div>

</ Div>

But I can not put the placeholder on the same line as the avatar.
(As on the Example screenshot)

How would you do it?

Best regards.

Eric
