wordpress上传图片不自动生成缩略图的解决方法

因为站点不需要显示这么多图片，只需要原图就OK了，所以就要修改下媒体设置。打开设置->媒体，将不需要的缩略图宽度高度都设置为0就可以了。如下图： <img title="wordpress上传图片不自动生成缩略图的解决方法" alt="wordpress上传图片不自动生成缩略图的解决方法" id="theimg" src="https://zhuji.jb51.net/uploads/img/202305/ec4f70691309248f8f02da1981731b2e.jpg" style="max-width:100%!important;height:auto!important;border: 1px solid rgb(204, 204, 204); vertical-align: middle; padding: 1px; overflow: hidden; max-width: 696px; width: 526px; height: 204px;"> 
但是这样设置之后，还是会生成其它分辨率的缩略图，笔者猜测应该是主题的问题，于是就去主题内查找，笔者用的主题是themolio。后来在主题文件的functions.php中找到了这样的代码：


<div style='margin: 3px auto 0px; padding: 0px 3px; outline: none; line-height: 21.6px; clear: both; border-width: 1px; border-style: solid; border-color: rgb(0, 153, 204); background: rgb(246, 251, 255); overflow: hidden; font-family: tahoma, arial, "Microsoft YaHei";'>
<div style="margin: 0px; padding: 0px; outline: none; float: right; line-height: 25.2px; font-size: 14px;">
复制代码
</div>
代码如下:</div>
<div id="phpcode1" style='margin: 0px auto 3px; padding: 0px 3px; outline: none; line-height: 25.2px; font-size: 14px; clear: both; border-right: 1px solid rgb(0, 153, 204); background: rgb(221, 237, 251); overflow: hidden; border-left: 1px solid rgb(0, 153, 204); word-break: break-all; border-bottom: 1px solid rgb(0, 153, 204); word-wrap: break-word; font-family: tahoma, arial, "Microsoft YaHei";'>
 
function themolio_setup() { /* 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'); /** 
* 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); /** 
* 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); /** 
* 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); register_nav_menu('primary', __('Primary Menu', 'themolio')); add_theme_support('post-formats', array('link', 'gallery', 'status', 'quote', 'image', 'video')); if(themolio_is_wp_version('3.4')) { 
add_theme_support('custom-background'); 
} else { 
add_custom_background(); 
} 
}</div>



其中add_image_size就是增加缩略图设置的方法，根据需要注释掉即可。其它主题也可以依此类推，只要搜索关键词add_image_size，应当就能找到缩略图的设置。

最后生成多张缩略图的问题就搞定了。

友情提示

如果日后有需要缩略图，可以在媒体->媒体库->选择需要的图片点编辑->编辑图片，然后就可以裁剪图片了。最后报下wordpress和使用主题的版本：

wordpress是3.4.1版本 
主题是Themolio，版本是1.2
