 * Hi,
    Can you tell me how the automatic thumbnails function works? Will it go 
   and grab it without user or admin intervention, or does an admin need to edit
   the Link post and click on the Generate Thumbnail and store locally? If a user
   uses the User Submission form, how do they trigger the generation?
 * Or is it possible to schedule some script in cron to trigger the Generate Thumbnail
   button inside the Library Configuration menu?`
 * Thank you

 * If you are referring to the option called ‘Use thumbnail service for dynamic 
   link images’, this function fetches images from the selected thumbnail generation
   site every time someone visits the page containing the Link Library. This can
   result in slower page loading times and might also exceed the limits of such 
   sites if you have a high-traffic website.
 * At this moment, the admin will always need to go into the link post and generate
   a thumbnail. This was meant as a quality-control mechanism so the admin can be
   sure that the thumbnail comes up correctly, and that visitors don’t make bad 
   content appear on their site if they are not moderating links before they appear.
 * I will see what could be done with having a schedulable cron job.
