如何为图像添加宽度和高度

I don't know much about coding, so could you help me with the right code to specify the width (285px) and height(143px) for this image?

$html .= '<img class="' . esc_attr( $args['thumb_align'] ) . ' rpwe-thumb" src="' . esc_url( $image ) . '" alt="' .  esc_attr( get_the_title() ) . '">';

Many thanks!

You can add height and width using style attribute

$html .= '<img class="' . esc_attr( $args['thumb_align'] ) . ' rpwe-thumb" src="' . esc_url( $image ) . '" alt="' .  esc_attr( get_the_title() ) . '" style="heigth:143px; width:285px;">';

OR

$html .= '<img class="' . esc_attr( $args['thumb_align'] ) . ' rpwe-thumb" src="' . esc_url( $image ) . '" alt="' .  esc_attr( get_the_title() ) . '"  heigth="143px" width="285px">';

This might help you

add an id parameter into your image tag the simplest way then using following code you can set the width and height. there are two options indeed. first u may want to use inline css to edit this like

document.getElementById("your image's id").style.width="285px";
document.getElementById("your image's id").style.height="143px";

or you may want just to use html attributes those i dont recommend

document.getElementById("your image's id").width="285px";
document.getElementById("your image's id").height="143px";
