设置WordPress相册图集galleries默认的图片大小

站长朋友们在使用wordpress 建站的过程中会发现，默认情况下，wordpress内置的相册图集（galleries）会使用完整尺寸（full）大小的图片。在很多情况下，我们想要使用其他尺寸。今天我们就介绍一下设置wordpress相册图集（galleries）默认的图片大小的方法。

切换到主题目录，打开 functions.PHP 文件，加入以下代码：

Crayon-5c891cca38ae7361084178" class="Crayon-Syntax Crayon-theme-classic Crayon-font-monaco Crayon-os-pc print-yes notranslate" data-settings=" minimize scroll-mouSEOver" style=" margin-top: 12px; margin-bottom: 12px; font-size: 12px !important; line-height: 15px !important;">

您只需要修改第 4 行的 medium 为您想要的图片尺寸即可。
