This plugin hasn’t been tested with the latest 3 major releases of WordPress. It may no longer be maintained or supported and may have compatibility issues when used with more recent versions of WordPress.

Mouseover Gallery


Mousover gallery splits the content into two columns where the right part contains the thumbs and the left part contains the enlarged image created by moving the mouse over the thumbs.

If you split the content-division manually by two div-tags with class names right_part and left_part resp you can place your textual content inside the columns and befor oder after the ones. For instance:

Some text or anything else
<div class=”left_part”>Some text or anything else</div>

<div class=”right_part”>Some text or anything else[gallerymo]Some text or anything else</div>

You can change the design by using the gallery options in the preference menu of the dashboard or by CSS in your style.css. There you have to use the !import-feature for overwriting element-styles.

  1. Upload Mouseover Gallery directory to the /wp-content/plugins/ directory.
  2. Activate the plugin via the Plugins menu.
  3. Configure your new gallery via the Settings > MOGallery menu.

  4. For better results please update you WordPress default images sizes for Thumbnails and Medium sizes to match your chosen Image Gallery Reloaded settings (also view FAQ)

  5. Divide your content into two divs with classes left_part and right_part and put the shorthand [gallerymo … parameter as in standard gallery] into the div right_part.


What images does the gallery use?

The plugin does not use the default image you upload, instead it uses the Medium and Thumbnail versions of it. It is done in order to produce better image quality and to increase performance. The size of these versions are set at Settings > Media. And why is it important? Because if you are running a photo blog or simply plan to use a very big gallery you may need to update the size of you Medium and Thumbnail versions of the image. The default sizes are 300X300 px and 150X150 px respectively. If you plan to set the main image to 960X700 px and/or use larger thumbnails it might be a good idea to set these sizes at the Settings > Media as well.

How do I add galleries to posts?

Remember, Mouseover Gallery uses the default WordPress Gallery feature.

  • Write a new Post or edit an existent.
  • Add images to it via the default Upload/Insert >Add an Image.
  • On the Add an Image popup click the Gallery tab, Click Insert Gallery and watch your new gallery set.
