Describe your issue or idea

The out-of-the-box settings for content type 'Post' have the format of the display of the image field set to 'Image style: Large' and the setting for this image style allows upscaling. If the user is unaware of this it can be a surprise, particularly if the user puts a constraint on the dimensions of the uploaded image field.

Steps to reproduce (if reporting a bug)

Either upload an image smaller than 800x600 in the image field for a post or set a constraint on the image field so that in uploading the image is scaled to a size smaller than 800x600.

Actual behavior (if reporting a bug)

The smaller image will be upscaled with consequent loss of resolution.

Expected behavior (if reporting a bug)

I would expect the image not to be upscaled by default.
