Petro SEO Images to WebP converts your existing JPEG and PNG attachments to WebP in bulk, then serves them on the front-end through the standard <code><picture></code> element with a full responsive <code>srcset</code>. The original files stay untouched on disk, so reverting is as simple as flipping a switch.
Designed to be small, dependency-free and predictable. No external services, no images uploaded anywhere, no opaque queue.
<h4>What it does</h4>
<ul>
<li>Converts every registered image size (full + thumbnails) to <code>.webp</code> next to the original (e.g. <code>photo.jpg</code> → <code>photo.jpg.webp</code>).</li>
<li>Wraps <code><img></code> tags from <code>wp_get_attachment_image()</code> and <code>the_content</code> in <code><picture><source type="image/webp">…</picture></code>, preserving full <code>srcset</code> and <code>sizes</code>.</li>
<li>Skips images automatically if a previous run failed because of filesystem permissions, so you can retry on demand without reprocessing the whole library.</li>
<li>Ramps the WebP quality down (75 → 60 → 45 → 40) when the encoded file ends up larger than the original, so you never ship a “WebP” that is heavier than the JPEG.</li>
<li>Idempotent: re-running the bulk job only touches new or updated images.</li>
</ul>
<h4>What it does NOT do</h4>
<ul>
<li>It does not delete or modify your original JPG/PNG files.</li>
<li>It does not require Imagick or a specific image library beyond what WordPress already uses (<code>wp_get_image_editor()</code>).</li>
<li>It does not phone home, register endpoints, or load remote scripts.</li>
</ul>
<h4>Privacy</h4>
The plugin processes images locally using WordPress’s built-in image editor. No data is sent to third-party services.

If you want a special adaptation to the needs of your page, you can commission me at <a href="http://BMo-design.de/kontakt/" rel="nofollow ugc">BMo-Design</a>.
This is stable version 1.8.0. Since the code of NextGEN Gallery was massivly changed in version 2.0.X, I decided to develop a new version of my plugin. You can download it at <a href="https://wordpress.org/plugins/bmo-expo/" rel="ugc">https://wordpress.org/plugins/bmo-expo/</a>.
<h3>Options</h3>
More Options can be set in the post/page tag:

For Example: ‘[scrollGallery id=1 start=5 autoScroll=true]’
Of Course you can change the style, borders and colors! Go into the plugin-folder “nextgen-scrollGallery” there you will find a folder “css” and the “scrollGallery_greyDesign.css”. 
Here you can add custom css designs, like the “scrollGallery_greyDesign.css”. 
I recommend to copy your “scrollGallery_customDesign.css” in your theme folder. Because if you make a update of the plugin, the “css” folder will be replaced. 
After you save a css-file in this “css” folder, it will be possible to change the style of the gallery in the admin interface.
The dimensions of thumbnails and images can be changed in your NextGEN Gallery plugin.
Since version 1.5 the do_shortcode() function is supported and since version 1.6 you can use [sG_thumbsSolo id=xxx] and [sG_imagesSolo id=xxx] instead of [scrollGallery id=xxx] to show only thumbs or images.
Since version 1.7 it is possible to set links to thumbs and images. To set a link, go into your NextGen Gallery and edit the image descriptions. If you write: [scrollGallery thumblink=”http://www.bmo-design.de” thumblink_target=”_blank”] you will set an external link to my page, which will open in a new window (target=”_blank”). 
Also you can set image links and image targets. Here’s an example with all the possibilities: [scrollGallery imglink=”http://www.bmo-design.de” thumblink=”http://software.bmo-design.de” imglink_target=”_self” thumblink_target=”_blank”].
