upPrev use a “Featured image” as a picuture. You can’t change it on “upPrev setting page”.
Use filter: Filter Reference / iworks upprev get the post thumbnail to change thumbnail.
Or use action Action Reference / iworks upprev image to add default thumbnail.
If I use filter: Filter Reference / iworks upprev get the post thumbnail, it replaces the featured image with the post thumbnail. If there is a featured image but no post thumbnail, there is no image in upPrev.
How can accomplish:
– Use featured image if there is one
– Else use post thumbnail
Dear peter-a
There was a mistake in http://upprev.com/documentation/action-reference/iworks_upprev_image
replace “return” to “echo”.
