 * I have no idea what to do here… I’m getting all of these issues how do I fix 
   them?

    optipng: Missing gifsicle: Missing pngout: Missing Install automatically
   | manually – Pngout is free closed-source software that can produce drastically
   reduced filesizes for PNGs, but can be very time consuming to process images

 * Looks like you probably need a newer version of PHP since you are missing the
   fileinfo extension that is included with PHP 5.3+. Check with your webhost to
   see if there is a way to change your PHP version, and/or get the fileinfo extension
   loaded.

 * All the JPG files will be processed no problem. It would just be PNG and GIF 
   files that you can’t compress since you are missing optipng and gifsicle. If 
   you don’t care, then you can just disable them on the Advanced tab.
 * If you can’t update PHP or enable fileinfo, you can always use the EWWW IO API
   at [https://ewww.io](https://ewww.io) but that is totally up to you.
