 * these appear in the plugin status box at the top of the optimizer settings page
 * Graphics libraries – only need one, used for conversion, not optimization: GD:
   OK   Imagemagick ‘convert’: MISSING
    safe mode: Off  exec(): OK   Only need one
   of these: finfo: MISSING  getimagesize(): OK  mime_content_type(): MISSING
 * does this impede performance of the plugin?

 * If the optimizers (jpegtran, optipng, etc) are all showing up, then you’ll be
   just fine with that.

 * thank you…
 * if I’m getting this kind of feedback from GT Metrix concerning our image optimization,
   which settings on EWWW must I be sure to effect? (there are so many settings,
   I don’t know which ones to toggle on)
 * RECOMMENDATION GRADE TYPE PRIORITY
    Optimize images F (45) 74% Images High What
   does this mean? Optimizing the following images could reduce their size by 121.5KiB(
   26% reduction).
 * Losslessly compressing [http://ctktexas.com/wp-content/themes/silverorchid/images/main_bg.png](http://ctktexas.com/wp-content/themes/silverorchid/images/main_bg.png)
   could save 28.6KiB (82% reduction). See optimized version

 * To get the first image (in your theme folder), you’ll need to run the Scan and
   Optimize on the Bulk Optimize page.
 * Most of the performance testing sites also expect you to strip metadata, so make
   sure you have that option turned on too.
 * I just did some new videos for 2.0, you might want to check them out:

 * thank you for these videos
 * I’ve inititated the bulk optimization as you recommended. It’s been “interrupted”
   twice though. Any idea why that might be happening?

 * This usually indicates one of two things:
 * 1. The connection between you and your webserver is dropping
    2. Your webhost
   is killing the process for excessive CPU usage
 * In the case of #1, it is difficult to do much about, but 2.0 will have a 30 second
   timeout instead of dying immediately. I don’t expect to release that this week
   though, so if you’re in a hurry, you’ll just have to keep slogging through.
 * In the case of #2, I recommend using a 5-second throttle to try and avoid causing
   issues on a shared webserver.
