You can specify the small version of the image by appending s to its base URL.

smaller image version https://i.stack.imgur.com/Brjd7s.jpg

Some images may have an ultra-small version of the image, accessed by adding ss, thus making it https://i.stack.imgur.com/Brjd7ss.jpg,
but your image does not have one.

Here is the list of all the modifiers for dimensions (not all are always available) :

  • s: Small Square (90×90) as seen in the example above
  • b: Big Square (160×160)
  • t: Small Thumbnail (160×160)
  • m: Medium Thumbnail (320×320)
  • l: Large Thumbnail (640×640)
  • h: Huge Thumbnail (1024×1024)
