Assuming that what you want to leave out is the class specification
and assuming that post.image will be nil if there is no image (replace
that with something similar as necessary)
<h2 <%= "class=/"ti-gallery/"" if post.image %> >
<%= link_to post.title, post %>

I have split it onto multiple lines to make it easier to read, that
will not affect the displayed page. The result of the code
"class=/"ti-gallery/"" if post.image
will either be the class= string or nil.
