 * Hi,
 * Thanks for this plugin. I have a few questions before I install this plugin on
   the live site.
 * I have 100,000 Posts. Many of which are missing featured image. Can you tell 
   me how much RAM will this plugin use?
 * Can I run some posts every hour? Using cron or something else? Because I am sure
   the server will crash if I run this on 100000 posts.
 * Do the feature images stay when the plugin is removed?
 * And Does it work fine with cache plugins?

 * Since it is processed by Ajax one by one, I think that it works even if the number
   of cases is large. However, the processing speed is slow. In my test environment,
   processing 2000 out of 100,000 took about 76 minutes.

 * I don’t use wp-cron. There is no function to run hourly.
 * > Do the feature images stay when the plugin is removed?
 * This plugin only sets the featured image. Even if you delete the plugin, the 
   image of interest in the post will remain the same.
 * > And Does it work fine with cache plugins?
 * I think it works, though it depends on the cache plugin.
    Testing with the WP
   Super Cache plugin worked fine.

 * I used this plugin but the images are not showing. I only see blank feature images.
 * The actual URL of the images are working, but WordPress back end only showing
   default gray page image.
 * How do I remove the feature image entries that this plugin added to database?

 * This plugin only sets the Featured image. Nothing else will be changed.
