 * Hey – I have a site that is using ‘Offload S3’ to store images with Amazon S3
   along with Amazon Cloudfront as a CDN. The Imsanity plugin works well when processing
   images at upload time, however, I have many images that were uploaded before 
   installing Imsanity which need to be resized. When I go to batch process the 
   images, I receive a ‘not writable’ error. I am sure this is an issue with the
   permissions on S3 but I am not quite sure what to do. Anyone have experience 
   with this?

 * Is that the WP Offload Media from Delicious Brains? If so, it is only officially
   supported with our other plugin, EWWW Image Optimizer.
    Optimizing images on 
   S3 requires that you have a local image to compress/resize, and also that you
   can get the local file-system path. Imsanity doesn’t have the logic necessary
   for either of those.

 * Ah – I see. Thank you for the quick response! I will check out EWWW.

 * So, I am trying EWWW and it seems that it can only compress images on S3. I don’t
   see any way to resize them. Is this correct or am I missing something?

 * If you enable “resize existing images”, the bulk optimizer will apply the dimensions
   you specify to the images on S3.
