Indeed, you are right; hence my question. 😁

I found myself referring to this gist a lot over the years for the sake of reducing the size of gigantic images when I put them in PR descriptions, so I've turned this into a simple Shortcut:

When you upload or copy/paste a raw image, github markdown will put in the rendered img tag the style max-width: 100%, so, it's mandatory to add the width and the height attributes for the img tag, any other thing will be removed by the renderer, so, only replacing the markdown with the img html tag adding the width and height will work.

{: width="50%"}

Still does not work in github repo readme. The {: width="50%"} part just does ignore.

The syntax for images with a specified width has changed over time.

HTML image tags are the way to go

height="450px" works for me. Thanks!

Just throwing in the Obsidian's image format

![[<url>|400]]

// Here 400 is the width

@mahendranv : Can you give an example with full syntax since your example doesn't work? Thanks

@uupaa
I couldn't get any of the suggestions to function on GitHub.

img tags work fine though.

<img src="https://media1.tenor.com/m/ofDuH0hvGh8AAAAd/so-what-do-you-think.gif" width="200" title="Ray Romano saying What do you think?" alt="Ray Romano saying What do you think?"/>

Update: Except that markdown linters dislike inline HTML tags. 😞

can we round the image border?

@rahaaatul
It appears not.
I tried to use CSS styles via Preview, but they're stripped off.
Plus the official statement from the markup repo (as seen below).

Note

The HTML is sanitized, aggressively removing things that could harm you and your kin—such as script tags, inline-styles, and class or id attributes.

HTML image tags are the way to go

Agreed... 100%.

GitHub (or markdown) syntax for images seems to be unstable, or else changes pretty frequently.

Going forward, a healthy mix of HTML image tags and anchor links seems the best approach (Example).

[
    <img
        src="MY_SRC_HERE" 
        width=70%
        title="My Image"
        alt="My Image"
    />
](MY_LINK_HERE)

The following worked well for me

<p align="center">
    <img src="assets/image.png" alt="Description" width="300">
</p>

The centring container is optional of course

That's all fine and well except that markdown linters don't like inline HTML...

I found that out the hard way today. 🤷 😐

If you want all your images to automatically resize to 150 x 150 pixels in the README.md with no additional HTML or CSS in GitHub, the following steps worked for me:

1. Upload image(s) to your repo.
2. Go to to where your image is saved in you repo using your browser. Notice the image size is just a preview and not the actual size.
3. Right click and select copy image.
4. Edit and paste in the README.md(use browser to edit).
5. Github briefly shows !!Uploading image.. in the editor then it changes ![image](https://github.com/user-attachments/assets/ffggfg-3202-0000-fdfd-somerandomnumbers
6. Go to preview before you commit to check the image size which is now ~150 x 150 pixels in the readme.md file.

Additional Notes I noticed no matter how large your image is, GitHub image preview in the browser is ~610 x 610 pixels but if you manually copy and paste the image into README.md file it automatically goes to 150 x150 px . You can copy any image from any page on the web and paste it in the README.md, it does the same thing. Be sure to copy image and not image address. I used google Chrome browser for the above steps.

Is this the online repo on GitHub?

3. Right click and select _copy image_.

Hello @crissyg,

I wasn't able to duplicate this "preview" behavior with GitHub in my web browser.
What am I doing differently than you're describing?

For example I don't see a preview for these icons at vscodium.
https://github.com/VSCodium/vscodium/tree/master/icons/stable

Or at GitHub docs.
https://github.com/github/docs/tree/main/contributing/images

Thank you!

Hi @mjbear ,

I clicked on one of the icons first. Example below:

https://github.com/VSCodium/vscodium/blob/master/icons/stable/codium_clt.svg

@crissyg
Thank you for the response.
Awesome.
There is certainly a small preview for SVG images as you've demonstrated.

I can't seem to get that to work for PNG or JPG though.
https://github.com/github/docs/blob/main/contributing/images/repository-fork-button.png
https://github.com/github/docs/blob/main/contributing/images/fastly_purge.jpg

@mjbear You're welcome and yes you're right about .jgp and .png files. Those are showing the actual sizes and not automatically resizing like the .svg files. I've been using svg for icons mostly . But you could convert jpg to svg using https://www.freeconvert.com/jpg-to-svg and then try it that way or resize each jpg/png using html like in the previous posts. <img src="image_location/image_name.png" width="10%"/> and change the width percentage to your liking. Example <img src="https://github.com/github/docs/blob/main/contributing/images/fastly_purge.jpg" width="10%"/>

All of the purely Markdown solutions seem to be broken on GitHub now, seen in the example:

It looks only the HTML tags work for manually resizing an image...

Sadly, looks broken like @nhooey pointed out.
Just joining the ranks here.

Confirm it's sadly still broken.

Markdown alone doesn't support resizing images, but you can try this (some platforms support it):

![Description](image.jpg){width=300 height=200}

However, this syntax is not widely supported. Using HTML (<img>) in your markdown file is more reliable.

<img src="image.jpg" alt="Description" width="300" height="200">

It worked for me. Thanks @kaecy

{width=300 height=200}

Doesn't work for Github comments tho RIP

@Laoode
Yep, when resizing images in Markdown, HTML tags are the way to go (until/unless something changes).
A bit unfortunate since Markdown linters don't care for inline HTML... 🤷‍♂️

@kaecy That worked for me in an Issue post, thanks.
