I have a classified image that is roughly 400 KB and every time export the image to Google Drive it's roughly 300 KB as a cropped image. Strangely, the first time I exported to drive the image was full size. Thereafter it was cropped. Code below. Any ideas how to export the full size image consistently?

Export.image.toDrive({
  image: classified2011,
  description: 'LandUse2011',
  scale: 30.0
});

    You're going to need to add more code than this. There's a "Get Link" button at the top of the code editor, and you can cut and paste that to let people run your code directly. (Only, probably you want to remove the piece of code that downloads.)

You will have to set the argument 'region' and define the region you want to export (probably you can just draw a polygon/rectangle). If you don't do that, the image will export as big as the size it is on your screen, see the explanation below:

region (Geometry.LinearRing|Geometry.Polygon|String, optional): A LinearRing, Polygon, or coordinates representing region to export. These may be specified as the Geometry objects or coordinates serialized as a string. If not specified, the region defaults to the viewport at the time of invocation.
