<h3>General Settings</h3>
<p>The plugin performs a check to make sure your system has the programs we use for optimization: jpegtran, optipng, pngout, and gifsicle. In some rare cases, these checks may erroneously report that you are missing the required utilities even though you have them installed.</p>

<h3>Conversion Settings</h3>
<p>
Conversion is not available in NextGEN or GRAND FlAGallery.
By default, all images have a link available in the media library for one-time conversion. Turning on individual conversion operations below will enable conversion filters any time an image is uploaded or modified.<br />
<b>NOTE:</b> The plugin will attempt to update image locations for any posts that contain the images. You may need to manually update locations/urls for converted images.
</p>
<table class="form-table">
