Rails: show images without image tag

Question

I want to show images without using <%= img_tag %>. So I tried following things

<img src="/images/bg/1.jpg" >
<img src="assets/images/bg/1.jpg" >
<img src="assets/bg/1.jpg" >
<img src="bg/1.jpg">
<img src="/bg/1.jpg">

This does not show the image. But if I do this

<%= image_tag("bg/1.jpg") %>

This works. But why it does not work with img tag. How can I make this work?

My image location app/assets/images/bg/1.jpg

Note:

<%= image_tag("bg/1.jpg") %>
outputs
<img src="/assets/bg/1-ed0a6edfcc008f66c22373e3d57a5c01.jpg" >

generated image link is not exactly the original image name

Answer 1

You need to generate link through image_url if you really want to use the plain img tag instead of fancy image_tag by Rails, and here is how:

<img src="<%= image_url('bg/1.jpg') %>">
