Load small thumbnail version of raw image resource

I have a web app that has a gallery of images that are loaded from a GitHub repo, e.g. https://raw.githubusercontent.com/.../image.png. The gallery shows the images as small thumbnails, with an enlarged version available on hover. The image sizes are fairly large, and there are many of them, making the total bandwidth used to load them in the order of MBs.

I was wondering if GitHub supports linking to down-sized images via the url, like some other websites do, e.g. image.png?w=100 or something like that.

Preemptive note, I know how to resize images in HTML/CSS/Markdown/etc. This is about reducing the actual size/bandwidth of image data loaded from the GitHub servers.
