Editing image output with get_image_tag()

Hey all,

I’m trying to edit the output that the “add media” button adds to a post when you’re writing it. I’m fairly successful so far, but I’m having an issue with two items in the function.

So basically, I’m just altering the get_image_tag() (from media.php) to add some extra sans and such to the image in question. I’ve got it working, insofar as the function work, and it returns the new additions as you’re writing the post. However, I can’t seem to obtain the size and alignment of what’s being posted.

Here’s what I have so far:

add_filter('get_image_tag', 'add_image_frames', 10, 2);
function add_image_frames($html, $id, size="medium") {
	list($img_src, $width, $height) = image_downsize($id, $size);
	$before = '<div class="image_frame align"><div style="background-image: url(\'' . esc_attr($img_src) . '\');"><span>';
	$after = '</span></div></div>';
	$html = $before . $html . $after;
	return $html;
}

So this is working great: when you click the “upload media” button while writing a post, and then insert it into the post, the <image> stuff is edited to add my “image_frame” div around it (and applies the actual image URL as the background style of the div). However, for the life of me, I cannot pull the proper size (it defaults to the one I gave it: “medium”, and although the <image> changes to the correct size, the size places in the div I’m adding remains at medium). If I remove the $size=”medium” from the function, then it reverts to “medium” anyway (because that’s the default for the function).

I also want to detect what alignment is given – alignleft, alignright – whatever – and add that to the “image_frame” div. But so far, it doesn’t add it either. For the life of me, I can’t figure out how to make this function grab what size and alignment is being chosen by the end user, and have it applied to my altered output. It just comes up blank every time.

Would anyone happen to know what I need to do to grab that information?
