Bulk option to change “Link type” in all albums

BEFORE doing the following you MUST upgrade to version 7.1.07.004 (to be released later today) or later, otherwise it will not work.

Put in the textfield of Tabe VIII-B98: Custom album proc: (copy-paste)

<?php
wppa_update_album( array( 'id' => $album['id'], 'cover_linktype' => 'thumbs' ) );

This is for changing it to thumbnails. Make sure it is one out of:

content
albums
thumbs
slide
page
none

Then click outside the textfield and wait for the green checkmark.
Then click Start! and wait until completeion. (a few seconds at the most).
Done.

Perfect, worked!

Thank you Jacob
