12120,Force Media Image Generation (for thumbnails),atow,,"It would be very useful to force the generation of a thumbnail images for uploaded files. With content being syndicated to feeds, e-readers, and mobile devices, the ability to have a working thumbnail is more important.

For example, if the original image has dimensions of 250x50, and the default thumbnail size in WP is 150x150, a thumbnail will not be generated because the 50 height is smaller than the 150 pixel minimum.

The fix would be to include an additional parameter to the image_resize_dimensions to allow the function the dimensions. A filter could be applied to allow the user to set which images should force the generation of a resized image (i.e. to exclude a medium and large image from being generated for a 250x50 image) by passing in the original width/height and max width/height.

in wp-includes/media.php

========

function image_resize( $file, $max_w, $max_h, $crop = false, $suffix = null, $dest_path = null, $jpeg_quality = 90 ) {

...

$force = apply_filters('image_resize_dimensions_force', $orig_w, $orig_h, $max_w, $max_h);
$dims = image_resize_dimensions($orig_w, $orig_h, $max_w, $max_h, $crop, $force);

========

function image_resize_dimensions($orig_w, $orig_h, $dest_w, $dest_h, $crop = false, $force = false) {
...

// if the resulting image would be the same size or larger we don't want to resize it
	if ( $new_w >= $orig_w && $new_h >= $orig_h && !$force )
