Optimizing only specific folders for "Optimize Everything Else"

Sure, just put the full system path to the wp-content/uploads/ folder into the ‘Folders to Optimize’ setting. It will skip over anything it has already optimized. If Aqua Resizer uses the built-in WP Image Editor functions, future images will be optimized automatically, but I don’t have any first-hand experience with that particular resizing library.

I see how that can be confusing, but it only scans your currently active theme, it does not scan the entire wp-content/themes/ folder.

Nope, sorry.

I realized this morning that there is a solution for your problem. The core function has this filter:

apply_filters( 'ewww_image_optimizer_bypass', false, $file );

$file is the full path to the file, and with that you could check to see if the file is within the themes folder (or whatever other folder you want to skip), and then return TRUE if it is.

If you need a more concrete example, let me know.

You would create file with a name like ewww-skip-theme.php and put it in the plugins folder (no need for a subfolder unless you prefer it that way). The entirety of the plugin would look something like this (and adjust the value of $folder_to_skip to your themes/ folder):

<?php
/*
Plugin Name: EWWW Skip Theme Scanning
Version: .1
*/

add_filter( 'ewww_image_optimizer_bypass', 'ewww_skip_theme', 10, 2 );
function ewww_skip_theme ( $bypass, $filename ) {
  $folder_to_skip = '/var/www/wordpress/wp-content/themes/';  // change this line with the appropriate path to the themes/ folder
  if ( preg_match( "/^$folder_to_skip/", $filename ) ) {
    return true;
  } else {
    return false;
  }
}

It will still scan the folder, the bypass happens right before the images get optimized. In your case though, the images are probably already optimized, unless you installed a fresh copy of your theme?

Tested it out myself, and realized there’s a problem with the pattern matching. The themes path has slashes in it, and we’re using those as the start and end of our pattern, which will not work. Replace those with pipes |, and it will work, like so:

add_filter( 'ewww_image_optimizer_bypass', 'ewww_skip_theme', 10, 2 );
function ewww_skip_theme ( $bypass, $filename ) {
  $folder_to_skip = '/nas/wp/www/cluster-42062/exampleinstall/wp-content/themes/enfold/';  // change this line with the appropriate path to the themes/ folder
  if ( preg_match( "|^$folder_to_skip|", $filename ) ) {
    return true;
  } else {
    return false;
  }
}

@yaniv691, you were probably right that it didn’t look like it was skipping them. When it actually works, it should say “Optimization skipped”
