How do you apply allow-stretch to all sitecore media img tags?

Question

How do I make it so that the "allow-stretch" property is applied to all of the tags that sitecore creates when inserting media from the media library?

I understand that you can set the allow-stretch property using the individual <sc:image> tags, but I want this setting to be applied globally so that whenever a user inserts media from the media library onto the page, the generated tag already has the "as=1" property applied to it by default.

Currently, whenever a user inserts media from the media library in my web application, the image tag created by sitecore looks something like this:

<img alt="" height="500" width="709" src="~/media/EAF03CA5568245B59FDDCC4B8FBD83E4.ashx?h=500&amp;w=709" />`

but I want it to look something like this:

<img alt="" height="500" width="709" src="~/media/EAF03CA5568245B59FDDCC4B8FBD83E4.ashx?h=500&amp;w=709&as=1" />

Notice that the second img tag that i provided has as=1 at the end.

Does anyone know how to make this happen?

I'm using Sitecore 6.5

You can create your own implementation of MediaProvider and set AllowStretch to always true. Inherit from Sitecore.Resources.Media.MediaProvider and override the GetMediaUrl() method:

namespace MyCustom.Media
{
  public class MediaProvider : Sitecore.Resources.Media.MediaProvider
  {
    public override string GetMediaUrl(MediaItem item)
    {
      Assert.ArgumentNotNull((object) item, "item");
      return this.GetMediaUrl(item, MediaUrlOptions.Empty);
    }

    public override string GetMediaUrl(MediaItem item, MediaUrlOptions options)
    {
      options.AllowStretch = true;
      return base.GetMediaUrl(item, options);
    }
}

And then in config patch the media provider to your custom implementation:

<mediaProvider type="MyCustom.Media.MediaProvider, MyCustom.Kernel"/>

EDIT: As Maras has suggested, try overriding the overloaded GetMediaUrl(MediaItem item, MediaUrlOptions options) method too.
