Html style to align an image to the right of an input box

How can I align the image in the below div to the immediate right of the
artist text box ?
<div id="artist"class="form-group">
@Html.LabelFor(m => m.Artists, new { @class =
"col-lg-2 control-label" })
<div class="container">
@Html.TextBoxFor(m => m.Artists, new { placeholder
= "Artist name",@class="form-control",
id="artistinput"})
<img onclick="AddArtist()" id="plusartist"
src="\Content\bootstrap\img\plus-button.png"
class="img-thumbnail"/>
@Html.ValidationMessageFor(m => m.Artists)
</div>
