@igorskyflyer not sure if you can inject css files, but if you can, you could try css variables with media queries.

The style attribute gets stripped out...

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.

alt{: 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

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

img tags work fine though.

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.

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. 🤷 😐
