I want to confirm that this plugin DOES work in version 3x Gossamer Links. I was able to get the attachment to display on a static page using the following on Detailed.html template:
<img src="<%att_url%>">
<%endloop%><br><%endif%>And it displays a public image.
Code:
<%if link_has_attachments and viewable_attachments%> <%loop link_attachments%> <img src="<%att_url%>">
<%endloop%><br><%endif%>
