 * Hello,
 * I am loving your plugin and your service! Thanks for such a great product!
 * Question: If we also purchase your PS plugin, and use it to export optimized 
   images from PhotoShop, then upload the images to WP, will the WP plugin still
   try to optimize the images that were already optimized in PS, resulting in being
   charged for those image optimizations? Or, can the the WP plugin tell that the
   images are already optimized, and thus not to try to further optimize them?
 * Thanks!

 * Hi,
 * Thanks for the compliments!
 * To answer your question, the WordPress plugin currently always assumes that the
   image that you upload in WordPress is not optimised yet. Therefore, if you would
   upload an image that’s already optimised with our Photoshop plugin (or website
   for that matter) to your WordPress site, our plugin will still attempt to optimise
   it.
 * We could make it smarter by storing some extra metadata in the optimised images,
   but that would make the images a bit bigger again, which we try to prevent.
 * What you could do instead perhaps, is enable the WordPress plugin so you can 
   bulk compress the existing images in your Media Library so that all your current
   images are optimised. If you then decide that it’s handier or cheaper to use 
   our Photoshop plugin, you can easily disable the plugin, so that new images (
   that are then already optimised) are not processed again.

 * One more question: Using the WP Plugin only, if you do the compress all to option,
   then later go through and do the compress all option again, will the plugin further
   compress the images it’s already done in the past, degrading the quality, or 
   are they marked somehow so the plugin knows to skip over items it has already
   done before?

 * For each image in your Media Library that is compressed with our plugin, we store
   metadata information in the WordPress database. In this we store which sizes 
   have been compressed, and what the resulting file size is for each size.
    When
   you for example add additional sizes to be compressed, our plugin would notice
   that, and only compress the newly added sizes.
 * Since it also stores the file size of the resulting compressed image in the metadata,
   changing the file on the filesystem would result in the image being compressed
   again.
 * In case you don’t change anything to the images on the filesystem, then bulk 
   compressing your images again should only compress missing sizes. In cases all
   your images have all image sizes compressed, and it shows this in the Media Library
   under the list view, then compressing again will not do anything to your already
   compressed sizes, and it will not count in your monthly totals.
