greg9885I've been struggling with this for quite some time now. I've tried a couple of plugins that deal with displaying custom fields in rss feeds. I can't seem to get any to work except for Kafkaesqui's plugin here. However, it only displays the img src, not the actual image. What/where can I manipulate the code to have an image displayed?
Here is the plugin code:
<?php
