Can't link to image with HTML on Rails app

I'm developing a Web app using Ruby on Rails. I have an image to add to the site, and I tried using the "img src" HTML tag to call a local image, but it won't work. If I use ruby to call it using the "image-tag" method, it works fine. I'm just wondering as to why it never works with HTML.

For example, I add an image to app>assets>images>image1.png

On the View file, I add HMTL as follows:

 <img src="/app/assets/images/image1.png">

It doesn't load

Yet if I enter this code in the same spot:

<%= image-tag: "image1.png" %>

It works fine.

Does anyone know why this is happening? I know I have a workaround, but I would rather know why my HTML tag has an issue with local files, yet links to files on the internet just fine. I'm new to coding. Cheers!

If you want use img tag you should:

<img src="<%= asset_path('image1.png') %>"/>

Without "/images" and "/".

The problem is the path you're using. Here's the short version: Remove app/ from the image URL, and it should work as expected.

If you run the app with the working code, you can see that this is what image_tag is already doing for you behind the scenes by inspecting the HTML. You should see something like this:

<img src="/assets/images/image1.png">

Updating your img tag to use that path should resolve the issue.

However, you should be using image_tag if possible! Without delving too deep into the technical details, if you deploy your site to production with the image_tag version and take a look at the HTML, you'll probably see something like this:

<img src="/assets/images/image1-[sequence of characters].png">

This will help ensure that clients are removing stale assets from their caches as necessary - the technical details can be found here (see section 1.2). If you hard-code the image, you're going to miss out on any features provided by the asset pipeline.

Looks like your syntax is incorrect for the image_tag helper. Try this:

<%= image_tag "image1.png" %>

Nice question. The Rails asset compiler is important but makes some problems like this one.

The asset compiler is likely adding a cache fingerprint to the file name. You can use <%=asset_path('images/image1.png')%> as the value of the src attribute, or continue using image_tag.

See the Rails guide assets document for more information.

Does that help?

can you try with a online based example ? My guess is ruby isn't finding your image within the directory.

<img src ="https://upload.wikimedia.org/wikipedia/commons/thumb/3/32/Googleplex_HQ_%28cropped%29.jpg/250px-Googleplex_HQ_%28cropped%29.jpg"> </img>
