Hi, thanks for the reply :) Apologies if my explanation wasn't clear, I'm not very proficient with PHP and had tried to knock something together myself which seemingly was wrong! I will explain more clearly...
I'd like to have a custom template with this code in:
<?php get_image_feed_list("http://www.example1.com/rss,http://www.example2.com/rss2", 10, "myImagesList"); ?>
And have the URL part generated by a custom field on the post/page the custom template has been assigned to.
Hopefully that is simple to achieve? I have done something similar before but the custom field was not put within a section of php so I was able to figure it out then :)
Thanks again for any advice
