* WordPress API for media display.

* Scale down the default size of an image.
12
* This is so that the image is a better fit for the editor and theme.
14
* The $size parameter accepts either an array or a string. The supported string
15
* values are 'thumb' or 'thumbnail' for the given thumbnail size or defaults at
16
* 128 width and 96 height in pixels. Also supported for the string value is
17
* 'medium' and 'full'. The 'full' isn't actually supported, but any value other
18
* than the supported will result in the content_width size or 500 if that is
21
* Finally, there is a filter named 'editor_max_image_size', that will be called
22
* on the calculated array for width and height, respectively. The second
23
* parameter will be the value that was in the $size parameter. The returned
24
* type for the hook is an array with the width as the first element and the
25
* height as the second element.
28
* @uses wp_constrain_dimensions() This function passes the widths and the heights.
30
* @param int $width Width of the image
31
* @param int $height Height of the image
32

33
* @param context Could be 'display' (like in a theme) or 'edit' (like inserting into an editor)
