If you'll look in your /forum/includes/functions_gallery_imageedit.php file for this code:
Code:
Content visible to verified customers only.
And replace it with this:
Code:
Content visible to verified customers only.
Then that should take care of the problem with any newly uploaded images. Then if you'll go to the Maintenance section of your vBa Gallery options and run the option to update your usernames then that should take care of any current images for you.
