Anything in the <code>public</code> folder is accessible at the root path (<code>/</code>) so change your img tag to read:

<pre><code>&lt;img src="/images/rss.jpg" alt="rss feed" /&gt;
</code></pre>

If you wanted to use a rails tag, use this:

<pre><code>&lt;%= image_tag("rss.jpg", :alt =&gt; "rss feed") %&gt;
</code></pre>

blocks|key|1179411|text|在Ruby+on+Rails项目中，默认情况下，服务器的HTML源代码的根目录是public目录。所以你的链接应该是：|type|unstyled|depth|inlineStyleRanges|entityRanges|data|1179412|<img+src="images/rss.jpg"+alt="rss+feed"+/>|code-block|syntax|javascript|1179413|但在Rails项目中使用内置帮助器是最佳实践：|1179414|<%25=+image_tag("rss.jpg",+:alt+=>+"rss+feed")+%25>|1179415|这将创建正确的图像链接，如果您添加断言服务器，等等，它将与这些工作。|1179416|entityMap^0|0|0|0|0|0^^$0|@$1|2|3|4|5|6|7|O|8|@]|9|@]|A|$]]|$1|B|3|C|5|D|7|P|8|@]|9|@]|A|$E|F]]|$1|G|3|H|5|6|7|Q|8|@]|9|@]|A|$]]|$1|I|3|J|5|D|7|R|8|@]|9|@]|A|$E|F]]|$1|K|3|L|5|6|7|S|8|@]|9|@]|A|$]]|$1|M|3|-4|5|6|7|T|8|@]|9|@]|A|$]]]|N|$]]

In a Ruby on Rails project by default the root of the HTML source for the server is the public directory. So your link would be:

<pre><code>&lt;img src="images/rss.jpg" alt="rss feed" /&gt;
</code></pre>

But it is best practice in a Rails project to use the built in helper:

<pre><code>&lt;%= image_tag("rss.jpg", :alt =&gt; "rss feed") %&gt;
</code></pre>

That will create the correct image link plus if you ever add assert servers, etc it will work with those.

blocks|key|1179442|text|当使用新的拼音时，图像文件夹将转到文件夹应用程序上的资产文件夹|type|unstyled|depth|inlineStyleRanges|entityRanges|data|1179443|将您的图像放入image文件夹后，使用|1179444|<%25=image_tag("example_image.png",+alt:+"Example+Image")%25>|code-block|syntax|javascript|1179445|entityMap^0|0|0|0^^$0|@$1|2|3|4|5|6|7|K|8|@]|9|@]|A|$]]|$1|B|3|C|5|6|7|L|8|@]|9|@]|A|$]]|$1|D|3|E|5|F|7|M|8|@]|9|@]|A|$G|H]]|$1|I|3|-4|5|6|7|N|8|@]|9|@]|A|$]]]|J|$]]

When using the new ruby, the image folder will go to asset folder on folder app

after placing your images in image folder, use

<pre><code>&lt;%=image_tag("example_image.png", alt: "Example Image")%&gt;
</code></pre>

blocks|key|1179466|text|只需使用img标签帮助器即可。Rails知道要查看资产管道中的图像文件夹，您可以这样使用它|type|unstyled|depth|inlineStyleRanges|entityRanges|data|1179467|<%25=+image_tag+"image.jpg"+%25>|code-block|syntax|javascript|1179468|entityMap^0|0|0^^$0|@$1|2|3|4|5|6|7|I|8|@]|9|@]|A|$]]|$1|B|3|C|5|D|7|J|8|@]|9|@]|A|$E|F]]|$1|G|3|-4|5|6|7|K|8|@]|9|@]|A|$]]]|H|$]]

simple just use the img tag helper. Rails knows to look in the images folder in the asset pipeline, you can use it like this

<pre><code>&lt;%= image_tag "image.jpg" %&gt;
</code></pre>

blocks|key|1395026|text|它对我很有效：|type|unstyled|depth|inlineStyleRanges|entityRanges|data|1395027|<%25=+image_tag(+root_url+%2B+"images/rss.jpg",+size:+"50x50",+:alt+=>+"rss+feed")+-%25>|offset|length|style|CODE|1395028|​|1395029|entityMap^0|0|0|2A|0|0^^$0|@$1|2|3|4|5|6|7|L|8|@]|9|@]|A|$]]|$1|B|3|C|5|6|7|M|8|@$D|N|E|O|F|G]]|9|@]|A|$]]|$1|H|3|I|5|6|7|P|8|@]|9|@]|A|$]]|$1|J|3|-4|5|6|7|Q|8|@]|9|@]|A|$]]]|K|$]]

It's working for me: 
<code>&lt;%= image_tag( root_url + "images/rss.jpg", size: "50x50", :alt =&gt; "rss feed") -%&gt;</code>

blocks|key|1395092|text|朋友，image_tag是完成这项工作的最佳方式|type|unstyled|depth|inlineStyleRanges|entityRanges|data|1395093|entityMap^0|0^^$0|@$1|2|3|4|5|6|7|D|8|@]|9|@]|A|$]]|$1|B|3|-4|5|6|7|E|8|@]|9|@]|A|$]]]|C|$]]

image_tag is the best way to do the job friend

I would like to add an image in my template for my ruby on rails project where i currenly have the code <code>&lt;img src="../../../public/images/rss.jpg" alt="rss feed" /&gt;</code> in a the layout <code>stores.html.erb</code> file however this doesn't seem to load as it looks like its missing a route which i'm not sure what its supposed to be. 

Any ideas please?

我想在我的ruby on rails项目的模板中添加一个图像，其中我目前在布局stores.html.erb文件中有代码<img src="../../../public/images/rss.jpg" alt="rss feed" />，但是这似乎没有加载，因为它看起来缺少一条我不确定它应该是什么的路线。有什么想法吗...
