Using the latest versions of WP and this plugin, I can't get any custom images to work/appear.
I've uploaded images via the relevant upload fields. On completion the upload field on the main form remains empty. This goes for all the image type(header, footer, etc).
If instead I select an image from the media library, and click the use this button, the entry on the main form still remains empty.
It seems to be some sort of bug.
