The <code>marquee</code> is not supported in modern html. Chrome dropped support for it a while ago. You need to implement this via CSS3 or Javascript.

Further W3C states that it is <a href="http://www.w3.org/wiki/HTML/Elements/marquee" rel="noreferrer">non standard</a> and should not be used. 

The effect can be easily acheived via <a href="http://remysharp.com/demo/marquee.html" rel="noreferrer">jQuery</a> or via <a href="http://www.w3.org/TR/css3-marquee/" rel="noreferrer">CSS3</a>

Because the <code>marquee</code> tag is a crime against nature. And it's no longer supported in newer versions of Chrome.

Replace the text with the image.

blocks|key|2346480|text|marquee元素有不同的实现，部分原因是没有发布它的规范。在HTML5中，元素是精确定义的，并且HTML5草案需要对marquee+as+defined+there的支持。(草案也声明它是“过时的”和“不符合规范的”，但这些只是他们对作者所说的；对实现的要求是不同的。)但是，在支持方面仍然存在限制和差异，请参见例如MDN+on+marquee。|type|unstyled|depth|inlineStyleRanges|offset|length|style|CODE|entityRanges|data|2346481|在这种情况下，导致问题的似乎不是图像，而是属性behavior="alternate"。如果你移除它，图片也会在Chrome上移动。|2346482|这显然是实现错误，而不是缺乏支持。在Chrome中检查DOM显示，behavior属性具有指定的值alternate，但它就是不起作用。如果在CSS中向marquee元素添加边框，图像将交替开始移动，但仅向左和向右移动几个像素。|2346483|如果你真的想换个方向，最好使用其他的技术来代替marquee。例如，可以使用JavaScript实现一个简单的运动图像，以便使用计时器在循环中改变位置，然后您也可以轻松地实现交替方向。或者，您可以使用CSS3动画，这可能更简单，但不是很健壮(由于浏览器支持的限制)。|2346484|entityMap|0|LINK|mutability|MUTABLE|url|http://www.w3.org/TR/html5/obsolete.html#the-marquee-element-0|1|https://developer.mozilla.org/en-US/docs/HTML/Element/marquee^0|0|7|1N|7|4M|7|1N|O|0|4F|E|1|0|N|K|0|X|8|1D|9|24|7|0|N|7|0^^$0|@$1|2|3|4|5|6|7|V|8|@$9|W|A|X|B|C]|$9|Y|A|Z|B|C]|$9|10|A|11|B|C]]|D|@$9|12|A|13|1|14]|$9|15|A|16|1|17]]|E|$]]|$1|F|3|G|5|6|7|18|8|@$9|19|A|1A|B|C]]|D|@]|E|$]]|$1|H|3|I|5|6|7|1B|8|@$9|1C|A|1D|B|C]|$9|1E|A|1F|B|C]|$9|1G|A|1H|B|C]]|D|@]|E|$]]|$1|J|3|K|5|6|7|1I|8|@$9|1J|A|1K|B|C]]|D|@]|E|$]]|$1|L|3|-4|5|6|7|1L|8|@]|D|@]|E|$]]]|M|$N|$5|O|P|Q|E|$R|S]]|T|$5|O|P|Q|E|$R|U]]]]

The <code>marquee</code> element has varying implementations, partly because there has been no published specification for it. In HTML5, the element is being defined exactly, and HTML5 drafts require support to <a href="http://www.w3.org/TR/html5/obsolete.html#the-marquee-element-0" rel="nofollow"><code>marquee</code> as defined there</a>. (The drafts also declare it “obsolete” and “nonconforming”, but these are just what they say to authors; the requirements on implementations are different.) However, there are still limitations and differences in support, see e.g. <a href="https://developer.mozilla.org/en-US/docs/HTML/Element/marquee" rel="nofollow">MDN on <code>marquee</code></a>.

In this case, it does not seem to be the image but the attribute <code>behavior="alternate"</code> that causes the problem. If you remove it, the image will move on Chrome, too. 

This is apparently implementation bug rather than lack of support. Inspecting the DOM in Chrome shows that the <code>behavior</code> property has the value <code>alternate</code> as specified, but it just does not work. If you add a border to the <code>marquee</code> element in CSS, the image starts moving, alternatingly, but just a few pixels right and left.

If you really alternating direction, it is probably best to use some other technique instead of <code>marquee</code>. For example, a simple moving image can be implemented using JavaScript so that the position is changed in a loop, using a timer, and then you can easily implement alternating direction, too. Alternatively, possibly simpler but not as robustly (due to limited browser support), you can use CSS3 animations.

Who said it doesn't ? 
On Chromium 83.0.4103.61 (Official Build) Built on Ubuntu , running on Ubuntu 18.04 (64-bit) it works flawlessly. 

Didn't test on Chrome, though.

I want to insert an image into marquee tag.

I have written following code:

<pre><code>&lt;marquee scrollamount="4" behavior="alternate" direction="right" width="300"&gt;&lt;img width="180px" style="padding-left:30px;opacity:0.7" src="img/cloud3.png"&gt;&lt;/marquee&gt;
</code></pre>

Its working fine in firefox and IE but not working in chrome.
What is the problem.?
Please reply as early as possible.
Thanks in advance.

why marquee tag not working in google chrome.?
