How can I scale an image in a Hugo page

JaredBusch

Currently, markdown does not natively have a way to scale images.

This seems to be an issues for me with using Hugo, I have an existing site that I am converting and the images are scaled with the normal <img> tag.

Searching the net, it seems a lot of tools have added functionality to markdown to support image scaling, but it seems Hugo's implementation of Markdown has not.

I tried to just use the HTML element in the Hugo page, but it was not rendered.

A shortcode is probably the easiest way to do what you want.

I stole this from here because I'm too lazy to write it myself. Just put this in layouts/shortcodes/image-resize.html

{{ $imagename := (.Get 0) }}
{{ $options := .Get 1 }}
{{ with .Site.GetPage "section" "media" }}
  {{ $original := .Resources.GetByPrefix  $imagename }}
  {{ with ($original.Resize $options) }}
  <img src="{{ .RelPermalink }}" width="{{ .Width }}" height="{{ .Height }}">
  {{ end }} 
{{ end }}

Then just add the image with:

{{< image-resize your-picture-name "150x150" >}}

@stacksofplates typo in your path there, but thanks!

@stacksofplates But this begs the question, how do I get a picture name?

where the fuck do I put image files? and do I then need to define them someplace else?

I know I canput things in static, but my understanding is to avoid that unless I really mean to add some static thing that is not programmatically built.

That or I am completely not understanding Hugo

That specific shortcode is looking for them in a media directory in your content folder. The name is the file name minus the extension.

That said I use static/images a good bit or what I've done a lot of the time is just use imgur.

Oops fixed. That's what I get for doing this on my phone.

Most Hugo themes have a way to add custom CSS properly, so that's my preferred method to changing visuals. And is a hell of a lot easier to maintain and write than trying to code all that other B.S. as in the solution. That's a huge turn off for me with Hugo as well as so many of the other annoyances. If it wasn't for the theme I found I'd be going back to WP or HTML template.

The problem with CSS for this is it it only works with one image or all of them. You'd have to continually add CSS properties for every image you create. The above solution is just a tag you write in your post. You just write the shortcode one time and then use it when you want to.

My personal opinion is that I think this is much easier to maintain. I don't have to manage a server, database, patches, plugins, worry about security of my system/CMS, etc or pay someone to do that for me. Every so often I'll have to write something like the above solution but it's not common and I don't have to manage anything. I can also redeploy the same site on literally anything because there's no backend to deal with.

Not saying I'm right and you're wrong, just that's why I really like this tool.

OH I thought he just wanted to do it to a single image. I guess I didn't read into it enough.

IMO, it would depend on the use case. In my case, the images I use in all posts should all be a certain width, and the height set to auto. So that's only once I put custom CSS, then one that targets the logo in the header, and one for the footer. Done. Super easy, and holy shit I would have never been able to figure out that shortcode stuff without my hand held, nor do I want to... Unless of course I need something that dynamic. Then sure.

On another separate note @stacksofplates, can this be done with anything? There is two places I need to edit in a partial HTML, and was a last resort. So I would rather this shortcode thing than that.

I could not get the shortcode to work last night.

I did download the entire example git repo and added all the pieces to my project and those worked.

As soon as I tried to use it on my about.md page, it never worked.

Can you "inspect element" in your browser of the image you are talking about and screenshot the whole hierarchy and I'll see if I can get the CSS going that you can add to the custom.css file in your other thread.

I took it all back out last night before i stopped. Tonight it is too late to fuck with, but I will next I work on this.

Specifying dimensions is a normal thing with images.

So, Hugo has a built in short code for this...

https://gohugo.io/content-management/shortcodes/#example-figure-input

{{< figure src="/images/dwarf1.jpg" alt="dwarf" width="100px" >}}

JaredBusch

Now to figure out how to make an image be to the left or right.

...and the figure shortcode allows the class attribute.. so that was easy. CSS can handle it.

in my dwarf.css

.about-left {
    float: left;
    padding: 0 20px 20px 0;
}

and the new shortcode

{{< figure src="/images/dwarf1.jpg" alt="dwarf" width="100px" class="about-left" >}}

Just an observation but I wonder what the "shortcode" is short for, when it's basically exactly the same as html?

<img src="/images/dwarf1.jpg" alt="dwarf" width="100" class="about-left">

In html when you provide width or height it's enough to do one of them and then that become the constraining factor and the image keeps it's aspect ratio..

Huog is all markdown based, and depending on the theme (apparently) you cannot jsut use html in a page.
