You can use several query string parameters in the url of the image to let Sitecore modify the image. The image has to be a Sitecore Media item.

Here is a list of the supported query string parameters:

  • w: Width in pixels
  • h: Height in pixels
  • mw: Maximum width in pixels
  • mh: Maximum height in pixels
  • la: Language (defaults to context language)
  • vs: Version (defaults to latest version)
  • db: Database name (defaults to context database)
  • bc: Background color (defaults to black)
  • as: Allow stretch (as=1)
  • sc: Scale by floating point number (sc=.25 = 25%)
  • thn: Thumbnail (thn=1)
  • dmc: Disable media caching, both retrieval and storage (dmc=1)

In your case you can use for example the ?as=1&w=600 to get the image resized to 600px width.

You can also do this programmatically to set the MediaUrlOptions when creating the mediaUrl:

var mediaOptions = new MediaUrlOptions {AllowStretch = true, Width = 600};
var mediaUrl = MediaManager.GetMediaUrl(mediaItem, mediaOptions);
