Hide an image in show.html.erb

I have the following "show.html.erb" script, and I get as an output TWO
images since I use a method to draw an image.

How can I HIDE the RESOURCE image?

Thanks.

Here is the script:

<canvas id="line" height="512" width="512">
</canvas>
<p id="notice"><%= notice %></p>
<p>
<b> Name </b>
<%= @dicom.name %>
</p>
<p>
<b> Image </b>
</p>
<p>
<%= image_tag @dicom.photo.url , :id => 'dicom_image' %>
</p>
<%= javascript_include_tag "coordinate" %>
<%= update_page_tag do |page|
page << "drawLine();"
end
%>
<%= update_page_tag do |page|
page << "drawImage();"
end
%>
<%= link_to 'Edit', edit_dicom_path(@dicom) %>
<%= link_to 'Back', dicoms_path %>

It worked when I did the following:

<div id="image_element" style="display: none;">
<p>
<%= image_tag @dicom.photo.url , :id => 'dicom_image' %>
</p>
</div>

Thanks.

...but never do that. Inline style attributes are poor practice. They
are hard to maintain, and clutter HTML markup with presentation
information.

Instead, define a CSS class with the appropriate attributes.

Better yet, if the element is always going to be hidden, remove it from
the HTML altogether.

Best,

Thanks Marnen for the advice.

Thanks @radhames. I really don't have knowledge yet in jquery. So,
that's fine. Thanks though.
