WordPress网站图片不生成缩略图 禁用多余缩略图教程

为确保WordPress站点的图片展示更为简洁，我们只需保留原始图片即可。因此，需要对媒体设置进行适当调整。请按照以下步骤操作：

1. 进入“设置”菜单，选择“媒体”选项。
2. 在媒体设置中，将不需要的缩略图的宽度和高度参数均设置为0，以禁用这些缩略图的生成。具体操作如下图所示：

尽管进行了上述设置，您可能仍会发现系统生成了不同分辨率的缩略图。这可能是由于主题设置所致。以我使用的Themolio主题为例，我在主题的`functions.php`文件中发现了相关代码：

function themolio_setup() {</p>
<p>    /* Make Themolio available for translation.
      * Translations can be added to the /languages/ directory.
      * If you're building a theme based on Themolio, use a find and replace
      * to change 'themolio' to the name of your theme in all the template files.
    */
    load_theme_textdomain('themolio', get_template_directory().'/languages' );
    add_editor_style();
    add_theme_support('automatic-feed-links');
    add_theme_support('post-thumbnails');</p>
<p>    /**
     * This sets up the image size for the grid based top-down layouts (with no sidebar).
     * If you change the width/height of your content,
     * you will have to modify the width and height mentioned below as well
     */
    add_image_size('themolio-two-col-grid-image-nosidebar',460,300,true);
    add_image_size('themolio-three-col-grid-image-nosidebar',290,200,true);
    add_image_size('themolio-four-col-grid-image-nosidebar',210,150,true);</p>
<p>    /**
     * This sets up the image size for the grid based top-down layouts (with sidebar).
     * If you change the width/height of your content,
     * you will have to modify the width and height mentioned below as well
     */
    add_image_size('themolio-two-col-grid-image-sidebar',356,250,true);
    add_image_size('themolio-three-col-grid-image-sidebar',230,150,true);
    add_image_size('themolio-four-col-grid-image-sidebar',171,110,true);</p>
<p>    /**
     * This sets up the image size for the featured image.
     * If you change the width/height of your content,
     * you will have to modify the width and height mentioned below as well
     */
    add_image_size('themolio-featured-image',800,300,true);</p>
<p>    register_nav_menu('primary', __('Primary Menu', 'themolio'));</p>
<p>    add_theme_support('post-formats', array('link', 'gallery', 'status', 'quote', 'image', 'video'));</p>
<p>    if(themolio_is_wp_version('3.4')) {
 add_theme_support('custom-background');
    } else {
 add_custom_background();
    }
}

`add_image_size`函数用于添加新的缩略图尺寸设置。您可以根据需要，通过注释掉相应的代码行来禁用不需要的缩略图尺寸。对于其他主题，您也可以通过搜索关键词`add_image_size`来定位并修改缩略图设置。

通过这些步骤，您应该能够解决生成多张不必要缩略图的问题。

友情提示：

如果您在未来需要生成缩略图，可以通过以下步骤操作：

1. 进入“媒体”->“媒体库”。
2. 选择您需要编辑的图片。
3. 点击“编辑”按钮，然后进行图片裁剪。

最后，附上我所使用的WordPress和主题的版本信息：

WordPress版本：3.4.1
主题：Themolio，版本：1.2

希望这些信息对您有所帮助！
