I’m having the same problem. The directory field isn’t even on the setting page after you choose it the first time. Doesn’t make sense.
Thanks for letting me know what you did. I’m having the same issue. Must be one of my plugins.
UPDATE: Of course, now it’s not happening anymore. I swear it was happening for about two weeks!
Shauno, your instructions worked for viewing gallery images on NextGen’s default Albums page. Now I’m trying to apply your guide to the related image thumbnails that NextGen can display below a single image in a post (I’m using tags to find them).
The controls for nggShowRelatedGallery() start in nggfunctions.php at line 710. I replaced the imageURL with ngg_custom_fields[“custom_link”] — where custom_link is the name of my custom field. However, this only links the thumbnails to the URL that I’m currently viewing.
This may be a more complicated hack than doing this for Gallery thumbnails. Thanks for your help! Here’s my site: michiganradiopictureproject.org
