 * Love this plugin! (already left a review)
 * I was just wondering if there was a particular reason you chose 90 for the default
   compression level? Is this relative to the standard jpeg compression values in,
   say, Photoshop? If so, 90 would be very high. I’d say 70 is more than enough 
   for most people.
 * Also, can I possibly put a request in to change the default width from 1200px
   to 1400? 1200 doesn’t quite pack enough punch for features such as sliders and
   full width themes.
 * Either way, keep up the good work!

 * Hi Phil,
 * Thanks for the feedback and kind review.
 * In regards to setting the default to 90 – because the image resizing process 
   is ‘destructive’ in that there’s no way to get back the original unresized image,
   I didn’t want to set this too low resulting in JPEG artifacts on the majority
   of resized images and therefore end up with an influx of _“your plugin ruins 
   my images”_ complaints. I felt that the compromise between high-enough quality
   and low enough filesize was around 90 (I had originally set it at 85 in v1.0 
   to v1.3). Then if the plugin user desired someting a little bit stronger, they
   can opt to reduce the value in the plugin settings, or (more preferably), use
   WordPress’ add_image_size() function to create images at the perfect size for
   particular locations in the theme (definitely give that function a look).
 * For the default width, I agree. I’ll bump up the default to 1400 in the next 
   release. What with the prevalence of sliders and larger screens these days, 1400
   seems more spot on.
 * Thanks

 * Phil —
 * How does your plugin do JPEG compression? Are you aware that WordPress compresses
   all uploaded JPEG images at 90% by default unless you create a filter to raise
   or lower this figure? (If you set it at 100% I believe it gets pointlessly recompressed
   at 100% rather than skipping compression.)
 * If your plugin passes a default of 90% to `jpeg_quality` it’s not doing anything
   WordPress isn’t doing already, and if it operates by a different method then 
   you’ve got bigger problems.

 * Hi,
 * Thanks for your concerns but you don’t need to worry.
 * 1. WordPress does *not* compress all uploads to 90% quality. By default, whenever
   you upload an image it will create thumbnails of it – those are at 90% quality(
   by default). The original image is left intact. As I’ve said before in other 
   threads and the readme, you should still use these thumbnails, along with add_image_size()
   to create appropriately sized images to use in your themes. These will still 
   be created adhering to the WordPress jpeg_quality setting. This plugin will only
   downsize the original uploaded image, including recompressing it at whatever 
   level you set in this plugin.
 * 2. As of version 1.7, this plugin uses in-built WP_Image functions to perform
   the resizing of the original uploaded image and so will respectively use the 
   best image resizing methods on your server.
 * Hope that helps,
    Phil

 * Thanks for explaining. I thought the compression rate was applied to the original
   and the thumbnails by both WordPress and potentially plugins like this.
