New features compared to CW Image Optimizer?
<ol>
<li>New plugin structure with many code rewrites and performance improvments</li>
<li>Bulk Optimization now uses ajax to optimize images and can handle huge amount of images. Bulk optimization tests were performed successfully on a 200k+ media library … yes it tooked a while to run the test, but it worked 🙂 whereas all image optimization plugins I had been testing were failing on a 15k+ media library !</li>
<li>Optimize function can now fix images meta if structure is not correct</li>
<li>Bulk Optimization can now be performed on All images or only the ones that haven’t been optimized yet</li>
<li>Save even more disk space with Lossy Jpeg Compression (Fallback to lossless compression if fails)</li>
</ol>
The WP Image Optimizer is a WordPress plugin that will automatically and losslessly optimize your images as you upload them to your blog. It can also optimize the images that you have already uploaded in the past.
Because WP Image Optimizer uses lossless optimization techniques, your image quality will be exactly the same before and after the optimization. The only thing that will change is your file size.
The WP Image Optimizer plugin is based on the WP Smush.it plugin. Unlike the WP Smush.it plugin, your files won’t be uploaded to a third party when using WP Image Optimizer. Your files are optimized using the Linux <a href="http://sourceforge.net/projects/littleutils/" rel="nofollow ugc">littleutils</a> and <a href="https://github.com/danielgtaylor/jpeg-archive" rel="nofollow ugc">jpeg-recompress</a> image optimization tools (available for free). You don’t need to worry about the Smush.it privacy policy or terms of service because your images never leave your server.
Why use WP Image Optimizer?
<ol>
<li>Your pages will load faster. Smaller image sizes means faster page loads. This will make your visitors happy, and can increase ad revenue.</li>
<li>Faster backups. Smaller image sizes also means faster backups.</li>
<li>Less bandwidth usage. Optimizing your images can save you hundreds of KB per image, which means significantly less bandwidth usage.</li>
<li>Super fast. Because it runs on your own server, you don’t have to wait for a third party service to receive, process, and return your images. You can optimize hundreds of images in just a few minutes.</li>
<li>Robust I needed a bulletproof plugin, able to handle thousands of files and working using cron-task with wp-cli. Most of the optimization plugins I had been testing failed, so I decided to build a new version of cw image otpimizer to suit my neeeds.</li>
</ol>
<h3>Troubleshooting</h3>
littleutils is installed, but the plugin says it isn’t. If you are confident that it is installed properly, then go to the plugin configuration page and disable the installation check.
It is also possible that your binaries aren’t accessible to your web server user (especially while using a cron task or wp-cli to create posts). You can link these binaries using the following commands:
<pre><code>ln -s /usr/local/bin/opt-jpg /usr/bin/opt-jpg

ln -s /usr/local/bin/opt-png /usr/bin/opt-png

ln -s /usr/local/bin/opt-gif /usr/bin/opt-gif

ln -s /usr/local/bin/tempname /usr/bin/tempname

ln -s /usr/local/bin/imagsize /usr/bin/imagsize

ln -s /usr/local/bin/gifsicle /usr/bin/gifsicle

ln -s /usr/local/bin/pngcrush /usr/bin/pngcrush

ln -s /usr/local/bin/pngrecolor /usr/bin/pngrecolor

ln -s /usr/local/bin/pngstrip /usr/bin/pngstrip
</code></pre>

Traffic Limiter is a useful addon for blogs with many media files which can cause high data traffic. 
There are three traffic limits to avoid over traffic costs: daily, weekly and monthly limit. If one of these limits is exceeded downloads will either be redirected to a custom URL or a custom message is displayed. For images you can define a fallback icon which is displayed instead of the message. Additionally a download bandwidth can be set for registered users and guests.
Also included is a statistic system which displays the current traffic consumption and individual file stats to see which media produces the most traffic.
All files are sent to the browser by a PHP script, supporting the most HTTP headers like <code>If-Modified-Since</code> (for caching) and <code>Range</code> (for partial downloads)
If the Apache extension <code>mod_rewrite</code> is installed download links stay the same, if not links to media files are automatically redirected. It is recommended to install <code>mod_rewrite</code>, although this plugin works without this extension.
Note: If you provide lots of downloads or media files you should try my download manager <a href="https://wordpress.org/extend/plugins/wp-filebase/" title="WP-Filebase" rel="ugc">WP-Filebase</a>.

Limits traffic and download bandwidth of media files. Additionally this plugin includes a download statistic system.
