I'm writing a wiki page on GitHub, and I'm using Markdown.
My problem is that I'm putting a large image (this image is in its own repository) and I need resize it.
I have tried different solutions, but they do not work:



[[http://url.to/image.png = 250x]]
Is there a way to get it?
It is preferable without HTML.
Markdown syntax for images (external/internal):

HTML code for sizing images (internal/external):
<img src="https://github.com/favicon.ico" width="48">
Example:
This should work:
[[ http://url.to/image.png | height = 100px ]]
