My question is: how can I make certain images be the first ones to be loaded? 我的问题是：如何使某些图像成为第一个要加载的图像？ Or how can I prioritise the way the images load on the page? 或者如何确定图像在页面上的加载方式的优先级？ By the way I'm doing this in html,php using javascript and ajax and the images are taken from a database. 顺便说一下，我正在使用javascript和ajax在html，php中执行此操作，并且图像是从数据库中获取的。
Thank you very much! 非常感谢你！

If you Base64 encode them, you can put them in the CSS, or HTML. 如果对它们进行Base64编码，则可以将它们放入CSS或HTML中。 It will really increase the side of a page, so perhaps encode a low resolution picture, and then replace it with highres when it loads. 它将确实增加页面的宽度，因此也许编码低分辨率的图片，然后在加载时将其替换为高分辨率。 That is, a preview image. 即，预览图像。
