** Resolved... **
If anyone else comes across a similar issue, I did this to hide the
delete link if no posts exist:
<% if Post.exists?(@posts) %>
<%= image_tag ("delete.png") %>
<%= link_to "Delete post",
{ :controller => "posts", :action => "delete",
:id => @posts },
:confirm => "Really delete this post? You cannot undo
this!" %>
<% end %>
