How to modify the attribute of a container element of jquery in Javascript?

Question

I have the following HTML:

<div id="tem_${temName}" class="tem-item gallery-item" style="display:inline-block">
<img class="nottohide" onerror="this.src='static/common_data/plus.png'" src="" height="150" width="100">
</div>

And this jQuery Container:
templateList = $('#pose_list');

How can I Manipulate the value of the src attribute of the <img> tag which in itself is nested in the <div> tag

Answer 1

$("img").src="" or $(".nottohide").src="" or $("div>.nottohide").src=""

I am not sure about the last one
