How to display image pointed by URL in Rails

I have a image here http://power.itp.ac.cn/~jmyang/funny/fun4.jpg an开发者_StackOverflow中文版d I want to display it in my Rails site. How should i do that?

You can also use the action view image_tag helper:

<%= image_tag 'http://power.itp.ac.cn/~jmyang/funny/fun4.jpg' %>

Alternatively you can just use the regular HTML tags:

ERB:

<img src="http://power.itp.ac.cn/~jmyang/funny/fun4.jpg">

Haml:

%img{ src: "http://power.itp.ac.cn/~jmyang/funny/fun4.jpg" }

Slim:

img src="http://power.itp.ac.cn/~jmyang/funny/fun4.jpg"

<%= link_to image_tag post.image %>

Put the URL into an img tag inside the view for the page that should display the image.

In my case, the image didn't show until I added alt attribute. So if that didn't work I think you can try this way.

<%= image_tag 'http://power.itp.ac.cn/~jmyang/funny/fun4.jpg', alt: 'fun' %>

Tested and worked.

<img src="http://power.itp.ac.cn/~jmyang/funny/fun4.jpg", width="500" , height="400"> </img>
