[Almost]

I made a plugin so that you can resize images in markdown specifically because of this thread.

The syntax is based loosely on the way iOS handles multple image sizes combined with normal markdown image embedding:
![alt text](http://someurl.com/someimage.png@<size>

Size can take the following formats:
100x200 - Absolute size
100x x200 - Absolute size where the other dimension is calculated to maintain aspect ratio
50% - Percentage
0.5 - Scalar Multiplier

So for example, my original picture:
http://cl.ly/image/2L3F1M2E1X3l/IMG_0136.JPG
is 1000x750.
All of the following would produce the same image at 1/2 size:
[white house](http://cl.ly/image/2L3F1M2E1X3l/IMG_0136.JPG@500x375)
[white house](http://cl.ly/image/2L3F1M2E1X3l/IMG_0136.JPG@500x)
[white house](http://cl.ly/image/2L3F1M2E1X3l/IMG_0136.JPG@x375)
[white house](http://cl.ly/image/2L3F1M2E1X3l/IMG_0136.JPG@50%)
[white house](http://cl.ly/image/2L3F1M2E1X3l/[email protected])

Install via npm:
npm install nodebb-plugin-image-sizer

Known Issues:
Images that are set to be wider than their container become elongated (width is set to match the container, but height is not adjusted). This means that mobile can get a bit dicey.
