Hi,
I've been all over the forums (and Google) trying to find an answer to this problem. I've seen plenty of people asking the same thing, with no definitive answer.
I'm moving a blog from one theme to another. The original blog has the post's "featured image" in a custom field called "posts settings". The new site has the featured image in Wordpress' default "Featured image".
When I export the .xml file from the old blog and try to import it to the new one, I don't get any "Featured images". I know that this is because they have different "meta_keys".
The old blog has:
<wp:meta_key>mainimg_medium</wp:meta_key>
<wp:meta_value><![CDATA[http://imageurl.com]]></wp:meta_value>and the new one has:
<wp:meta_key>_thumbnail_id</wp:meta_key>
<wp:meta_value><![CDATA[image ID number]]>I can't just find and replace "mainimg_medium" with "_thumbnail_id" because "_thumbnail_id" doesn't recognize URLs, it only recognises ID numbers.
Any help will be greatly appreciated,
Thanks!
